“THEN, as now, the economy was depressed and America was deporting Mexicans in droves. The year was 1932 and David Alfaro Siqueiros, a Mexican artist who now ranks with Diego Rivera and Jose Clemente Orozco as one of the three great Mexican muralists of the last century, arrived in Los Angeles. His visit was to prove unexpectedly short (seven months), but consequential. The tale is documented in an exhibition that has just opened at the Autry in Griffith Park in the city.”
