In working to dehumanize their enemies and establish Soviet Russia's superior morality, TASS artists often depicted Germans as sickly or beastly fiends, with blue skin or long nails. Sometimes they had these Germans ravaging a pure-looking, comely young maiden to accentuate the Nazis' depravity. In a different poster, a Nazi medic is shown shooting a wounded comrade to avoid having to treat him. While such a scenario was probably based off of only hearsay, the one shown in here was from a very real discovery near the end of the war, which vindicated much of what the Soviets had been saying about the morality of their enemies. This poster was done in reaction to the liberation of Nazi concentration camps, and focuses very intently on the blood that is on the Germans' hands. The large disembodied hands of whoever is giving the subject a medal, and the solid white reflection and grim expression of the man very clearly detach and dehumanize these two characters as two cogs in a brutal machine.
