Julio Gonzalez Pochoir Print ‘Tête Pilar’ (1942) - Printed in Paris by Daniel Jacomet, and published in 1957 by Berggruen & Cie for a show at their gallery.
(Jacomet worked with all the giants of the 20th century, Picasso, Leger, Miro, Chagall, etc. and the products of these collaborations are very collectable.
Julio Gonzalez was a childhood friend of Pablo Picasso. They collaborated closely on metal sculptures in the 1920s and 1930s, and Gonzalez became a noted artist in his own right.)
