OFTEN REFERRED TO as a cowboy cartographer (he was in fact also a cowboy) and the Renaissance Man of the West, Mora expressed himself in countless other ways as well. He also worked on all scales, including vast murals and an almost hundred-foot-long diorama he created for the 1939-40 Golden Gate International Exposition in San Francisco, Discovery of the San Francisco Bay by Portola, for exhibition in the California Pavilion.
Mora also illustrated for newspapers, wrote and illustrated children’s books, and published two major works in 1946, Trail Dust and Saddle Leather and Californios: The Saga of the Hard-Riding Vaqueros, America’s First Cowboys.
