This lively array of ferocious anti-Nazi posters produced in the Soviet Union during World War II will reward anyone interested in political cartoons, graphic design, wartime propaganda, German Expressionism, Soviet Social Realism or all of the above. The show follows a more extensive one at the Art Institute of Chicago last summer that was the first of its kind in this country. It presents 15 large posters by the little-known Okna Tass studio, a group of artists, poets and writers that coalesced in Moscow in the wake of Germany’s invasion of the Soviet Union in June 1941. Its members were tasked with combining phrases and images to inspire the Soviet people to fight the Germans in the face of seemingly insurmountable odds.
