'The Círculo de piedra adventure was born thanks to the friendship with Carlos Franqui, who was introduced to me by Wilfredo Lam. I was in Cuba, in 1967, in the middle of the cold war, I remember that there were cannons under my hotel. All of Carlos’s friends, including almost all the artists who would later create the Circulo de piedra three years later, were in Havana in ’67 for the Salon de Mayo congress. I remember [Asger] Jorn, [Wilfredo] Lam, César [Baldaccini], [Antoni] Tapies, my wife Rita Gallè, [Alexander] Calder, [Valerio] Adami, the critic Guido Ballo. On that occasion I met Fidel Castro, to whom I gave a copy of my edition made with Lam Apostroph Apocalypse. Castro subsequently organized a graphic exhibition at the Casa de las Américas…
What interests me remains of the Círculo de Piedra is the common spirit of familiarity with Carlos Franqui, mine, and of all the artists, in the years of exile from Cuba. The folder is born without a precise commercial purpose and neither is there a a union between artists and a movement… It was also born to support Carlos economically and that is why I left him a part of the edition. The portfolio is a project that–as you can imagine–has also cost a lot for the artists involved, but the enthusiasm for our work has led us to bear the costs of the edition and each of the 15 artists was left with a copy of the work, as a reminder of the common project. Mirò was printed by Maeght in Saint-Paul-de-Vence, Jorn by Bramsen in Paris, Calder I printed it, because he was in Milan for the exhibition at Studio Marconi.' —Giorgio Upiglio
