By his 70s, many paintings, ink drawings and prints have as their theme an old, grotesque dwarf as the doting lover of a beautiful young model. Jacqueline Roque (1927–1986) worked at the Madoura Pottery in Vallauris on the French Riviera, where Picasso made and painted ceramics. She became his lover, and then his second wife in 1961. The two were together for the remainder of Picasso's life. His marriage to Roque was also a means of revenge against Gilot; with Picasso's encouragement, Gilot had divorced her then husband, Luc Simon, with the plan to marry Picasso to secure the rights of her children as Picasso's legitimate heirs. Picasso had already secretly married Roque, after Gilot had filed for divorce. His strained relationship with Claude and Paloma was never healed. By this time, Picasso had constructed a huge Gothic home, and could afford large villas in the south of France, such as Mas Notre-Dame-de-Vie on the outskirts of Mougins, and in the Provence-Alpes-Côte d'Azur. He was an international celebrity, with often as much interest in his personal life as his art. Picasso was one of 250 sculptors who exhibited in the 3rd Sculpture International held at the Philadelphia Museum of Art in mid-1949. In the 1950s, Picasso's style changed once again, as he took to producing reinterpretations of the art of the great masters. He made a series of works based on Velázquez's painting of "Las Meninas". He also based paintings on works by Goya, Poussin, Manet, Courbet and Delacroix. In addition to his artistic accomplishments, Picasso made a few film appearances, always as himself, including a cameo in Jean Cocteau's "Testament of Orpheus" (1960). In 1955, he helped make the film "Le Mystère Picasso" ("The Mystery of Picasso") directed by Henri-Georges Clouzot. He was commissioned to make a maquette for a huge -high public sculpture to be built in Chicago, known usually as the "Chicago Picasso". He approached the project with a great deal of enthusiasm, designing a sculpture which was ambiguous and somewhat controversial. What the figure represents is not known; it could be a bird, a horse, a woman or a totally abstract shape.
