At this year’s Paris Photo, our representative, Robert Klein, of Robert Klein Gallery, included Pablo Picasso in his booth. A lingering visitor, looking intently at the print, turned out to be Picasso’s son Claude Ruiz Picasso, himself an artist – he was Richard Avedon’s photographic assistant for a spell.

Picasso was photographed in 1954. Read the story of the Sitting and see more photos.
