This is an outstanding book by my favorite art history professor and author. It was short but to the point, focusing on three authors - Rivera, Siqueiros, and Orozco and their work on display at MOMA in New York. It focuses on the cubism of Rivera, the surrealism of Siqueiros and the murals by Orozco. The comparisons focused on the same subjects were effective in conveying the similarities and differences among the painters.
