From Artfinder: Picasso, 'Nude Woman in a Red Armchair'. Picasso’s mistress Marie-Thérèse Walter was just 17 when she met the 46-year-old artist. She became one of three mothers to his 4 children... The curvaceous figure contrasts starkly with the jagged forms of Picasso’s earlier Cubist period. Her voluptuous build is echoed by the scrolling arms of the chair. The face is metamorphic; one lover, possibly Picasso, can be seen kissing another on the lips.
