The 1920s Investigator: painting Call of Cthulhu characters that look the year

A Call of Cthulhu investigator portrait is the trickiest horror commission I take, because the source material is not a fantasy. There is no armour to render, no glowing weapon to anchor the silhouette, no obvious monster shoulder-perched behind the character. The brief reads more like a 1920s portrait painter's brief than a TTRPG commission. Get the period wrong and the painting falls apart. Get the period right and the painting does something fantasy art simply cannot do — it asks the viewer to believe the character was photographed in a real year, in a real city, holding the real weight of what they have seen.

This piece is for the player about to commission a Call of Cthulhu portrait, the Keeper running a Pulp Cthulhu campaign who wants visual anchors for the cast, or the fan of the Lovecraft-derived genre who wants to understand why the 1920s setting changes everything about how a character gets painted. I will walk through the period look, the occupation visual cues, the Mythos-touched expression, the period-accurate gear, and the conversation about painting sanity loss without resorting to the obvious.

Why the 1920s setting matters

Call of Cthulhu, published in 1981 by Chaosium, is the second-oldest still-running TTRPG. The default campaign era is the 1920s, roughly the decade between the end of the First World War and the onset of the Great Depression. The Pulp Cthulhu and modern-era variants exist, but the canonical investigator is the 1920s one, and most commissions I get for the system land in that decade.

The setting matters because everything that is not there is doing as much work as everything that is. There are no smartphones. There are no fluorescent lights. There are no cars with electric ignition. There are no antibiotics in any practical sense. When a 1920s investigator pulls a revolver from a coat pocket, the weight of that gesture is different from the same gesture in a modern setting, because the investigator does not know if they will be alive next week and the revolver is the heaviest thing they own.

Yusra, a player whose first Call of Cthulhu campaign ran through autumn 2024, emailed me asking for a portrait of her character, an antiquarian named Helene Marchetti. Her first brief landed in my inbox with a reference image that was, frankly, a modern photoshoot in vintage clothing. The subject was wearing a cloche hat and a 1920s-style dress, but the lighting was studio LED, the makeup was contemporary, and the eyeline read as a 2020s influencer. We spent a kickoff call talking about why that reference would not work as a brief, and what we needed to put in its place. The result was a portrait that reads as a photograph from 1924, not a contemporary cosplay shot.

The visual language

A 1920s portrait announces its period through ten or so visual cues. Get most of them right and the painting works. Miss them and the painting reads as fancy dress.

The cues I look for:

• The hair. Short for women, in a bob or a marcel wave, often tucked under a cloche hat. Slicked-back and pomaded for men, usually with a side part. A 1940s pompadour is wrong. A 1950s teddy boy quiff is wrong. A modern undercut is very, very wrong.
• The collars. Stiff detachable collars for men's shirts. Round Peter Pan collars or low V-necks for women's day dresses. No polo necks. No band collars. No T-shirts visible under anything.
• The hats. Almost universally worn outdoors and frequently indoors. Fedoras, homburgs, flat caps, cloche hats, derby hats. The hat is doing class and occupation work as much as fashion work.
• The waistlines. Dropped waistlines for women — the dress flows from shoulder to hip without a defined waist, the silhouette reads as columnar rather than hourglass. Three-piece suits for men with waistcoats almost always visible.
• The shoes and stockings. Mary Janes, T-bars, and oxfords for women. Wingtip brogues and spectator shoes for men. Stockings are visible at the calf because of the dropped hemline — usually flesh-toned or pale grey.

The other detail I push every client on: the smoking. The 1920s was the decade when cigarettes went from a low-status habit to a near-universal one across classes and genders. A 1920s portrait that includes a cigarette holder for a woman or a lit cigarette for a man instantly reads as period. The cigarette is not glamorising the habit — it is a date stamp on the painting, the same way a flip phone in a portrait would date a piece to the early 2000s.

The sepia palette

The single biggest decision in a Call of Cthulhu portrait is the palette. Lovecraft's stories live in a particular visual register — sepia, ochre, faded indigo, the bone-white of old newsprint. The colour was leached out of the world for these characters. A portrait that uses contemporary saturation breaks the spell.

I paint Call of Cthulhu portraits in a tight palette of warm browns, deep ox-blood reds where they appear at all, faded indigos and slate greys, with the highlights pushed toward bone white rather than pure white. The skin is painted with a slightly higher yellow undertone than I would use for a contemporary portrait, which is what gives the painting that old-photograph read.

The 1920s investigator does not live in colour. They live in the colour of newspaper print that has been left out in the sun for too long.

That sounds restrictive. It is the whole point. The palette compression is what lets a Call of Cthulhu portrait sit next to a 1924 newspaper page and read as belonging to it.

What I do not do is paint the portrait fully monochrome, the way a literal sepia photograph would be. The colour stays in, just quieter. A subtle warmth in the cheeks, a deep red on the lipstick or the cufflink, the faintest blue cast in the shadows under the eyes. The painting is a colour painting, restrained.

Occupation as costume

The Call of Cthulhu rules sheet asks you to pick an occupation, and the occupation drives more of the portrait than the player usually expects. Four of the most-painted archetypes and the costume work that goes with each:

• The Antiquarian. Wool waistcoat over a soft-collared shirt, often without a jacket, sleeves pushed up to the forearm. Reading glasses pushed up onto the forehead. Ink stains on the right cuff. The painting almost always wants a book or a manuscript in the frame, but I usually push back on that — the suggestion of a desk behind the subject is enough, and an actual prop on the canvas reads as too literal.
• The Journalist. Three-piece suit, usually rumpled, with the waistcoat unbuttoned at the bottom. A press card in the hatband if a hat is in frame. A notepad held loosely in one hand, pencil tucked behind an ear. The journalist's costume reads as working harder than the suit suggests, and the painting should show that.
• The Doctor. A dark suit in the formal portraits, a white coat or surgical apron in the in-action pieces. Pince-nez or wire-rimmed spectacles. The doctor is usually painted with a more upright posture than the other occupations, and the lighting tends cooler — clinical rather than warm. I keep the medical equipment minimal. A stethoscope draped around the neck is enough. A scalpel in hand is a horror cliché.
• The Private Investigator. A fedora, a trench coat or a heavier overcoat depending on the city, a revolver visible only as the bulge in the coat pocket rather than in hand. The PI's portrait wants to feel watchful — the eyes do most of the work. The body is at rest. The face is not.

There are dozens of other Call of Cthulhu occupations and most of them paint similarly to one of these four. A professor reads like the Antiquarian. A reporter reads like the Journalist. A nurse reads like the Doctor with a softer palette. A police detective reads like the PI with a more formal silhouette. Pick the closest of the four as the anchor and adjust from there.

The Mythos-touched look

This is the conversation that makes Call of Cthulhu portraits different from any other period commission. The investigator has, at some point in the campaign, seen something. Maybe a deep one. Maybe a fragment of a manuscript that should not exist. Maybe a colour. The painting needs to register that the character has lost something, without resorting to literal monster imagery in the frame.

The cues I use:

• The eyes are too still. A character who has seen something looks at the viewer without quite tracking. The eyeline is a fraction off-centre. The whites of the eyes are visible slightly more than they should be.
• A pale streak in the hair. Period-appropriate, has lore precedent in Lovecraft's stories, reads instantly as something happened to this person.
• A hand that is doing something the face is not. The face is composed. The hand is gripping the chair arm, or the book, or the cufflink, just a fraction too tightly. The fingertips are slightly white.
• A wound or mark that the painting does not explain. A small scar on the temple. A burn mark on the forearm where the sleeve has ridden up. A pale band of skin on the wedding-ring finger of someone who has not removed their wedding ring voluntarily.

The Mythos-touched look is restraint. The painting that fails is the one that puts tentacles in the background, or eldritch sigils glowing through the subject's skin, or a green eldritch tinge on the lighting. That version of the painting is doing the player's work for them. The painting that succeeds shows a person who is one beat away from being fine, and the players at the table figure out the rest.

Period-accurate gear

For investigators with combat gear visible, the period accuracy of the firearm matters more than the player thinks. A 1920s portrait with a 1980s Glock in it is broken in a way the viewer feels even if they cannot name why.

The firearms that read as period:

• The Colt M1911A1 semi-automatic pistol. The most common American sidearm of the era. Boxy silhouette, distinct grip.
• The Smith & Wesson Model 10 revolver. The classic police revolver of the decade.
• The Webley Mk VI revolver. British investigators, especially ex-military.
• The Thompson submachine gun. For the Pulp Cthulhu register, with the drum magazine being the most iconic silhouette.
• The double-barrel shotgun. Cut-down or long-barrelled, ubiquitous across rural settings.

If a firearm is in the frame, I paint it with the same restraint as everything else — held at rest, in the lap or at the side, never raised toward the viewer. A 1920s portrait of a person aiming a pistol at the camera reads as cosplay. A portrait of a person sitting with a revolver in their hand, looking past the viewer at something the viewer cannot see, reads as Call of Cthulhu.

The other period gear cues are smaller but they add up: a brass key on a leather lanyard, a Kodak Brownie camera on a strap, a hip flask, a notebook, a fountain pen tucked into a waistcoat pocket. Choose two. Never more. The painting is a portrait, not an equipment list.

Painting sanity loss

This is the question every Call of Cthulhu client eventually asks, and the answer is almost always less than you think. Sanity loss in the painting is a question of degree, and the degree is set by the campaign moment the portrait is meant to anchor.

Three tiers:

• Pre-campaign. The investigator has not yet seen anything. The portrait reads as a normal 1920s portrait. The horror is implied by genre context, nothing on the canvas. This is the right brief for a player whose campaign has just started.
• Mid-campaign. Something has happened. The eyes are too still, the hand grips too tight, the pale streak runs through the hair. The portrait is unsettling on a second look. This is the most common brief.
• Late-campaign or post-incident. The investigator is visibly unwell. Sleep deprivation in the face, slight tremor implied in the line work, a posture that has rotated a few degrees off-vertical. This is the rarest brief and the hardest to paint without tipping into caricature.

I will paint any of the three. The conversation I have with the client up front is about which one. A portrait painted to the wrong tier looks wrong, and there is no rescuing it without a near-total repaint. Diego, a player whose campaign was in its tenth session when he commissioned the portrait, briefed me for late-campaign. We talked for three calls about the specific incident his character had survived, the specific sleep he had lost, the specific page of the manuscript he had read. The painting that came out of those calls is the one he says his Keeper now uses as the visual anchor for every flashback the character has.

Closing notes

A 1920s investigator portrait is a specialist piece, but it is also one of the most rewarding commissions I take. The constraint of the period, the restraint of the palette, the discipline of not painting the eldritch thing — all of that pushes the painting toward a register that fantasy commissions rarely reach. The result is a piece that hangs as well in a contemporary living room as it does next to a printed character sheet.

If you are running or playing a Call of Cthulhu campaign, the horror character art guide covers the wider gothic conversation. The historical character art guide covers period accuracy across non-fantasy commissions and is the closest sibling piece to this one. The eldritch horror design article covers the harder question of when to actually paint a Mythos creature, on the rare commissions where that is the brief. The character work service page has the closest portfolio references to a 1920s investigator portrait. When you are ready, the order form is where the brief starts. Mention which tier of Mythos-touched you want and which occupation your investigator runs. The kickoff call gets short and useful from there.

Call of Cthulhu is a Chaosium property. The studio paints investigator portraits as personal-use commissions for individual players and Keepers, never for commercial resale or publication.
