Jigsaw puzzle featuring Detroit Industry, north wall (detail), 1932?1933, mural by Diego Rivera (Mexican, 1886?1957). A mural painted for San Francisco?s Pacific Stock Exchange attracted the attention of the Detroit Institute of Arts, which commissioned him to paint the walls of its classical Garden Court. His theme, the manufacture of automobiles through human labor, pleased Edsel Ford, the president of the Ford Motor Company, who agreed to fund the project and became a great champion of the artist. The vast factory Ford built on the Rouge River, where Rivera spent days sketching, provided the images for the mural?s largest panels, including the one shown here.
