Between the 1960s and 1990s, more than fifty designers worked at OSPAAAL. 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.

From the 1960s, painter Raúl Martinez started working as a graphic designer, drawn to the social impact of posters and magazines. He was known for his portraits of well-known revolutionary icons, but to commemorate the 26th of July Movement he portrayed an anonymous Cuban patriot.
