OSPAAAL (Faustino Pérez), "Day of solidarity with the people of Venezuela," 1969.

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.

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.

In the context of Cuban posters, OSPAAAL was one of the most important poster-producing organizations:

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 posters typically feature translations in four of the UN-recognised official languages: English, French, Arabic and Spanish. The poster's subjects vary enormously, though all are united in their message encouraging viewers to take a day or week in solidarity.

OSPAAAL posters focused on international solidarity, supporting liberation movements worldwide - from Vietnam to Mozambique, Palestine to South Africa. They were designed to promote anti-imperialist struggles and Third World unity during the Cold War era.
