The Cheyenne were a very far-ranging people, especially once they acquired horses. Originally, the Cheyenne lived on the Great Plains of South Dakota, Wyoming, Nebraska, Colorado, and Kansas. Today, there are two Cheyenne tribes, one in Oklahoma and the other in Montana.

Curtis created forty-three (43) copper photogravure plates during his visits with the Cheyenne and thirty-five (35) remain available to collectors today.
