In 1937, in the middle of the Spanish Civil War, a poster pleaded for relief for a beleaguered Madrid. A photograph by Robert Capa (1913–1954) is an emotional appeal to everyone to put a stop to all war. Other posters tried to keep up the morale of the Popular Front against the Fascist forces by showing heroic images of farmers and workers. Meanwhile, didactic newspapers posted on the wall provided the international war volunteers with detailed instruction in combat techniques.
