Not much is known of Otis Thomas. What we do know is Otis settled in San Diego after serving in the armed forces in the Korean War. He was a man of modest means living on his veteran's income as well as earnings from his artwork. Many of his ideas were likely gathered from his journeys to the Arizona desert. Otis Thomas was commissioned to paint twenty-three Kachinas over a period of several years. Twenty-one of which have been consigned to Windsor Betts Art Brokerage in Santa Fe, New Mexico.
