David Harbour’s most detailed tattoo record belongs to Alexei Shostakov, the Red Guardian he plays in Black Widow. That distinction matters. The tattoos were designed for the character, and Harbour discussed several of them in interviews, but they should not be presented as proof that the actor permanently wears the same designs in ordinary life.

The ink is doing character work. Alexei has spent years in Soviet prisons, carries a loud communist identity, and thinks of Natasha and Yelena as his daughters even though the family was originally an undercover arrangement. The tattoo artists built those facts into separate pieces: names, faces, political figures, prison symbols and Russian-style ornament. Here is what each major tattoo shows and what Harbour has actually confirmed.

Natasha and Yelena are named beside Melina’s portrait

The most personal design on Alexei’s body is the family tribute on his upper arm and shoulder. It combines a portrait of Melina, the character played by Rachel Weisz, with the names Natasha and Yelena written in Cyrillic below or beside the image. The layout makes the point without dialogue: Alexei may call himself a super-soldier, but he also carries the people he treated as family.

Harbour said the Melina portrait was built from a younger image of Weisz, and he singled it out as his favourite tattoo. That comment explains why the portrait is more than a generic Russian prison mark. It is a character-specific reference to the woman who played Alexei’s wife in the cover story and to the complicated family the four agents created together.

The names are important as a separate detail. They are not simply decorative Cyrillic lettering around a rose. They identify Natasha and Yelena, and the film uses the tattoo as a quiet confirmation of Alexei’s attachment to both women. A wide screenshot can make the writing look like a dark band. A closer image shows the lettering and the portrait as two connected but readable parts.

KARL MARX and the knuckle lettering make the politics impossible to miss

Across Alexei’s knuckles are the words KARL and MARX. Harbour described the design as one of his favourite details because it is so blunt and funny. It replaces the familiar prison-tattoo idea of words such as “love” and “hate” with the name of the communist philosopher, turning Alexei’s politics into something he literally cannot hide when he holds up his hands.

The English lettering is deliberate. Alexei is a Soviet character, but the audience needs to read the joke instantly, so the design uses Roman letters rather than forcing viewers to decode a longer explanation. The placement also gives the tattoo a practical role in close shots. When Alexei gestures, the knuckles announce his ideology before he starts talking about Captain America or the glory days of the Soviet system.

Harbour’s interview makes this one of the best-supported tattoos in the article. The image establishes the placement and the interview establishes why the design was chosen. It is not the same as the Russian gang work elsewhere on the body, which is built from symbols, buildings and ornamental shapes rather than a readable name.

Lenin’s portrait turns the abdomen into a Soviet political panel

Alexei also has a portrait of Vladimir Lenin on his abdomen. Harbour named Lenin in interviews, and the placement gives the tattoo more presence than a small political emblem. It sits on the torso as part of the character’s larger Soviet identity, alongside chest decoration and the dense marks that suggest a long prison history.

The design is easy to miss when Alexei is wearing the Red Guardian suit. It becomes visible in the prison and shirtless scenes, where the camera has time to show how many separate pieces cover his torso. Lenin is not merely background texture. The portrait tells the audience that Alexei’s beliefs are personal, old-fashioned and theatrical, just like his obsession with being remembered as a national hero.

It is still worth keeping the distinction between the character and Harbour himself. The tattoo was created for Alexei’s body on screen. The fact that Harbour discussed the design means the production detail is confirmed; it does not turn the fictional Lenin tattoo into a permanent David Harbour tattoo.

The Melina neck portrait is a separate tattoo from the family names

Another portrait appears on Alexei’s neck: Melina’s face with the name Melina beneath it. Harbour described the image as a younger version of Rachel Weisz, and the tattoo gives the character’s relationship with Melina a visual shorthand. It is close to the face, easy to see in a side profile, and much more intimate than the large political imagery on the chest.

The portrait should not be merged with the Natasha and Yelena lettering simply because both designs are connected to the same family. The neck piece is a named portrait. The shoulder work is a group tribute. They support the same story from different angles: Melina is the person Alexei loved, while Natasha and Yelena are the daughters he continued to claim.

The shot also shows why production photographs are more useful than a generic celebrity headshot. The tattoo is small, partly affected by beard and lighting, and positioned where an angle can hide it. The close image makes the face and the word underneath easier to separate from the other prison-style markings.

Prison and Russian gang symbols fill the spaces between the named tattoos

Alexei’s body is covered with additional Russian prison-style work: architectural shapes, lettering, crests, birds and ornamental forms. Harbour said the design team researched Russian gang tattoos and then adjusted the imagery so it did not read as a distracting Nazi eagle. Small parapets and fortress-like details were added to give the image its own visual language.

Those markings are not one single tattoo with one single meaning. They are the background system that makes Alexei look as though he has spent years inside the prison world described by the film. Some elements imply status, ideology or confinement; others are there to make the skin look lived in. The production record supports the research and design intention, but it does not provide a private biography for every symbol.

The arm and chest markings also include a falcon-like design and a large double-headed eagle or crest shape in some frames. These are character imagery, not evidence of Harbour’s own political or prison history. They sit beside the named tattoos to make Alexei’s body read as a visual record of Soviet power, loyalty and time behind bars.

The tattoos also help separate Alexei’s public performance from his private disappointment. He talks about the Soviet Union as though the old system can still restore his status, while the family pieces show the people who matter to him after that status has gone. The writing on his knuckles is loud and ideological; the names and faces are quieter and more vulnerable. That contrast is why the tattoos feel like part of the character rather than a costume department joke.

The placement creates a second layer of storytelling. The knuckles appear whenever Alexei gestures. The abdomen appears when the prison scenes strip away the suit. The neck portrait is visible in profile, and the shoulder tribute appears when he wrestles or moves his arm. Each design was placed where the camera could reveal it at the right moment without stopping the film for an explanation.

The useful distinction is simple: Karl Marx, Lenin, Melina, Natasha and Yelena are identifiable references with production or interview support. The surrounding prison ink is a researched visual language whose individual symbols should not be over-translated. Read together, the pieces turn Red Guardian’s body into part of the story rather than a random collection of fake tattoos.
