During the Spanish Civil War (1936-1939), propaganda and visual communication became very important for the Republic attacked by nationalists rebels. It was necessary to create a strong link between all the people fighting the fascist menace. Even the trains were covered by propaganda posters. In Barcelona, many artists, who were communists, anarchists and socialists, formed a big syndicate. They confiscate a palace, and installed their workshop. 1800 people worked there. They produced bold colorful posters. During that war more than 10.000.000 posters were printed.
