 OSPAAAL stands for:

Organización de Solidaridad de los Pueblos de Asia, África y América Latina (Organization of Solidarity with the People of Asia, Africa and Latin America)

OSPAAAL was an international non-governmental organisation founded in 1966, which sought to hold dialogue with and reach activists across the globe. With representation from over 80 countries in the Global South, the Tricontinental Conference, held in Havana, Cuba in 1966, was a defining moment for the creation of OSPAAAL.

The OSPAAAL was founded in Havana in January 1966, after the Tricontinental Conference, a meeting of over 500 delegates and 200 observers from over 82 countries. Acting as the "key bridge" to unite liberation struggles and movements in the three continents.

From its foundation until the mid-1980s, OSPAAAL produced brightly coloured propaganda posters promoting their cause. These posters were folded and placed inside Tricontinental magazine for international distribution.

OSPAAAL was one of the most important Cuban poster-producing organizations, creating solidarity posters to support liberation movements and anti-imperialist struggles around the world during the Cold War era.
