ABSTRACT
He returned home in 1922 to work on the murals for the National Preparatory School, in a dual collaboration with Rivera and Xavier Guer rero, that extended to organizing the Union of Technical Workers, Painters and Sculptors, editing its paper El Machete until 1930 and writing its manifesto. That year he was imprisoned for six months for his part in the May Day marches, and began painting canvases. His first solo exhibition was at the Casino Espanol, Mexico City, in 1932. Exiled for political agitation, he painted murals on public and private buildings in Los Angeles, using industrial materials, including La America Tropical (Tropical America), airbrushed on the Chouinard School of Art and destroyed in 1932. In 1933 he was deported from the USA and travelled in the Southern Cone, painting an experimental mural with Antonio Berni and Lino Enea Spilimbergo for the Argentine newspaper publisher Natalio Botana.
