The exhibition presents about 70 works created by the three great masters: José Clemente Orozco, Diego Rivera and David Alfaro Siqueiros, leading figures of Mexican and international culture. Their art represented the Mexican artistic avant-garde within the framework of the most important movements of the twentieth century. This exhibition allows the visitor to learn more about the artistic practice of these three masters by presenting lesser-known works and experiments such as sketches for murals and large drawings.
