Between the 1960s and 1990s, more than fifty designers worked at OSPAAAL (the Organisation of Solidarity with the People of Africa, Asia and Latin America). Based in Cuba, they made magazines and posters that were sent around the world. Their aim was to promote radical political ideas. Many of their posters celebrate socialist revolutions and liberation movements from the Global South. They also criticised the foreign policy of the U.S.A. and supported the Black Power movement.
