The National Gallery of Art presents this Web site that reveals earlier works on the wooden supports and canvas of Picasso's painting The Tragedy, found during conservation treatments. Picasso said, "What comes out in the end is the result of the discarded finds." The artist often reworked his paintings, leaving clues on the surface to tip off viewers that another work might be covered up by the top layer of paint. For example, the texture of the surface paint of The Tragedy first indicated that there might be another painting beneath. Conservators found sketches from 1899 on the wooden supports of The Tragedy, and drawings and paintings on the canvas underneath the blues and greens of the finished 1903 picture -- in particular, a bullfight in reds and yellows done in 1901. In the last section of the site, a QuickTime movie summarizes the stages of the painting.
