Picasso's extraordinary energy culminated in the hundreds of etchings he produced in the 1960's with the Crommelynck brothers. In 1968, when Picasso was nearing his late eighties, he produced 347 etchings in only 6 months. Every type of intaglio technique was used in these prints, but he paid special attention to the sugar-lift aquatint. The first plate of the series Picasso, son oeuvre, et son public (lot 255) is the masterpiece of the group. Here you find a self-portrait, a clown with the head of Jean Cocteau, a strong circus man, a beautiful bareback rider and a reclining woman along with hundreds of spectators. The rest of the series is made up of images from the circus, subjects based on Ingres and La Célestine (subjects from Spanish picaresque novels). These next 67 lots show Picasso's incredible techniques and iconography.
