Throughout his career he was artistically influenced by his teacher Oscar Howe, a Yanktonai modernist. In college he encountered the painter Wayne Thiebaud, who exposed him to pop art. After graduating in 1964 he taught painting at the Institute of American Indian Arts in Santa Fe where he decided to paint Native Americans in a style he described as, “real, not red.”
Using real-life accounts as inspiration, he created controversial works which consistently fought against the tourism-driven themes that were typical of contemporary Native American art. Regarding the body of work that includes the Bicentennial Indian lithograph, he said, “The fact I have wrapped Indians in American flags is not a political statement, it’s what I’ve seen. At one point the Bureau of Indian Affairs shipped thousands of American flags out West and that’s what the Indians did with them.”
