Cover of OSPAAAL's Tricontinental 76

"OSPAAAL was founded in 1966 in Cuba after the Tricontinental Conference, to which Castro invited an international group of leftist leaders, with the aim of supporting the fight against imperialism and globalisation. Part of this mission was publishing a magazine, Tricontinental, which was distributed to revolutionaries worldwide. Folded into each issue was a poster. The posters would be dependent on a striking image. Often the typeface would be very small, used for some lines of text announcing a day of solidarity with people engaged in a fight against imperialism – in Vietnam, South Africa, Puerto Rico, and elsewhere. This was printed in three or four languages, usually Spanish, English, French and Arabic. The aim, as OSPAAAL’s artistic director Alfrédo Rostgaard once said, was ‘to create a means of communication that was immediate’. Although the magazine was meant for the current and future leaders of leftist organizations, the posters had to be able to speak to the workers who made up their potential supporters."— https://www.apollo-magazine.com/cold-war-cuba-ospaaal-posters/
