After 1930 a new vigor and bolder simplification appeared in his work. American art collector Albert C. Barnes convinced him to produce a large mural for the Barnes Foundation, The Dance II, which was completed in 1932; the Foundation owns several dozen other Matisse paintings. This move toward simplification and a foreshadowing of the cutout technique are also evident in his painting Large Reclining Nude (1935). Matisse worked on this painting over a period of several months and documented the progress with a series of 22 photographs which he sent to Etta Cone.
