Five-color poster. OSPAAAL (Organization of Solidarity with Asia, Africa, and Latin America) was born out of Mehdi Ben Barka and his associates' increasing observations of and frustrations with the widespread effects of colonialism, at the time highlighted by the Cuban Revolution, the Palestinian movement, and pro-sovereignty and anti-apartheid struggles on the African continent. Here, the organization calls for nuclear disarmament by commemorating the destruction of Hiroshima, avoiding nebulous jargon and directly calling it a "bombing" in four languages, as was usual for OSPAAAL printed matter. A clever printer's trick renders "Hiroshima Hiroshima" in a melted red. Slight creasing and few chips to edges. Near fine. (Measures 20 9/16 by 12 13/16 in.)
