This Soviet propaganda plate was dedicated to The Third International, also known as The Communist International or Comintern (1919–1943).
It was an international organization that advocated world communism. It was controlled by the Soviet Union and was tasked to “struggle by all available means, including armed force, for the overthrow of the international bourgeoisie and the creation of an international Soviet republic”.
The Comintern held seven World Congresses in Moscow between 1919 and 1935.
