This illustration by Homer Nelson appeared on a 1925 calendar as part of Brown & Bigelow's "Indian Heroine Series". The source photo by Beatrice Tonnesen was found at the Winneconne (WI) Historical Society. The illustrated detail of the headband is, more or less, faithful to the photo. Mary Simmonds O'Grady (1896-1976) is believed to have been the model.
However, I've always felt that Tonnesen was responsible for many more of the posed photographs of beautiful women dressed as Native Americans and illustrated by the nation's top calendar artists, in the rush to satisfy the public appetite for the genre in the 1910s, 20s and 30s.
