Perhaps we can think that mail art derives from Dada and link it to Fluxus, Filliou's proposal of an eternal network, and the highly innovative poetry and experimental art, born at the same time in different countries. GGMarx practiced collective creation, in poor areas of the southern cone of South America. In a broader and ideologically more sensitive context, a folk art appeared, thanks to the popular struggles in Cuba, México, Brazil, Chile, Bolivia, Peru, Nicaragua, Venezuela, Uruguay, Colombia, Ecuador and Argentina. The liberation movements, developed during the seventies, have marked the direction of Latin American mail-art intercourse. But they acquired their real strength in Argentina in 1976, when the Military Terrorist State was implanted and started the time of art = life.
