This commemorative poster celebrates OSPAAAL's 30th anniversary (1966-1996), featuring the iconic image of Che Guevara with stars representing the continents of solidarity (Asia, Africa, Latin America). The phrase "Hasta la victoria siempre" was Che's signature closing and became one of the most famous revolutionary slogans. The vibrant purple/magenta background with orange silhouette creates a striking pop-art effect, befitting OSPAAAL's legacy of powerful graphic design in service of international solidarity.
