In September 1908, Kahnweiler was a guest at a party thrown by Picasso in honor of Henri Rousseau in the upstairs of Le Lapin Agile. Attending this party were many who were part of the Montmartre art and cultural scene. He was admiring art with Gertrude Stein and Alice B. Toklas when Fernande Olivier introduced him to two young Americans, Indiana Jones and Norman Rockwell.
