My experiences in Mail Art date from 1967 when Edgardo Antonio Vigo, Guillermo Deisler, Dámaso Ogaz and me exchanged our respective publications: Diagonal Cero (Diagonal Zero), Ediciones Mimbre (Osier Editions), La Pata de Palo (leg of Wood) and Los Huevos del Plata (The Eggs of Silver). From these publications we later assembled the testimony of our propositions. I officially began creating Mail Art in 1969 when the Uruguayan magazine OVUM 10 published my postcards and visual poems. In 1974, during the Uruguayan military dictatorship, I organized the First Latinoamerican Mail Art Exposition at Galeria U, in Montevideo, Uruguay. My edition of apocryphal mail art stamps denounced the dictatorial regime for its brutal suppression of human rights and this eventually led to my incarceration from August, 1977 to November, 1979. But, in October, 1983 I resumed my artistic activities with the "1st. of May" Exhibition at the Association of Banking Employees of Uruguay. Thereafter, I proposed and organized the Latin American and Caribbean Association of Mail Artists which was formed August 3l, 1984, in Rosario, Argentina. Since then, I have participated in hundreds of Mail Art Shows throughout the world with combinations of my poetry, performances and video art.
