Jean-Pierre Vasarely (Yvaral) (French, 1934 - 2002) Op-Art Serigraph. Titled "Pyramid". He is the son of Victor Vasarely. Pencil signed lower right. Numbered (4/25) H.C. H.C. stands for hors commerce, or "not to sell." Often the H.C. impressions were used as exhibition copies, so that the works being sold were not over-handled or damaged. Sometimes these impressions differed from the editioned prints by being printed on different paper or inked differently. Yvaral studied graphic art and publicity at the ?cole des Arts Appliqu's in Paris between 1950 and 1953. In 1960, Yvaral co-founded the Groupe de Recherche d'Art Visual (GRAV) with Julio Le Parc, Fran?ois Morellet, Francisco Sobrino, Horacio Garcia Rossi and Joel Stein, seeking to develop a coherent abstract visual language composed of simple geometric elements. In 1975 he coined the phrase 'Numerical Art' to describe artwork composed (or programmed) according to numerical rules or algorithms. From this time onwards he used computers to digitally process and manipulate images, although the final images were always hand painted. He used this technique to produce several series of portraits starting from instantly recognizable images, such as the face of Marilyn Monroe, and processing them to the point where they become abstract compositions, while the original image remains recognizable.
