Donald Montileaux claims he has been a professional artist for just six years. But the artistic legacy of Montileaux, a 60-year-old member of the Oglala Lakota tribe, stretches across decades.

His first inspiration to become an artist came at an early age, Montileaux said, when his father would entertain him by drawing pictures of his favorite characters – Donald Duck and Mickey Mouse.
