The Detroit Industry fresco cycle is a series of murals painted by Mexican muralist Diego Rivera 18861957 as a tribute to the workers in manufacturing, the sciences, and agriculture of Detroit, Michigan, in the 1930s. Rivera completed the twenty-seven-panel work in eleven months, from April 1932 to March 1933. The fresco cycle spans four walls in Detroit Institute of Arts. It is considered the finest example of Mexican mural art in the United States, and the artist thought it the best work of his career.
