OCLAE (Roberto Casanueva), "Contra la penetración imperialista en las universidades," 1970. Offset poster

OCLAE stands for:

Organización Continental Latinoamericana y Caribeña de Estudiantes (Continental Latin American and Caribbean Organization of Students)

OCLAE is the Latin American and Caribbean Continental Organization of Students, which was founded in 1966 in Havana, Cuba. However, there's some discrepancy in the founding dates - one source mentions it was created in 1996, while another states it was founded in 1966.

According to one source, OCLAE was founded in 1966 in Cuba, with Fidel Castro and Ernesto Che Guevara proposing the organization to bring together students of Latin America and the Caribbean to discuss the reality in their countries.

OCLAE has played a significant role as a mobilizing and coordinating body for anti-imperialist struggles, promoting actions for the reform and democratization of education, the eradication of illiteracy, and the development of unity and solidarity among students across the continent.

So OCLAE represents a continental student organization that produced solidarity posters as part of its mission to unite Latin American and Caribbean students in anti-imperialist and educational causes.
