Acrylic Painting of Sioux Indian Chief, Running Antelope over $5 bills which feature his image. Running Antelope is the only Native American whose image was used on U.S. currency. The photographer changed his Sioux headdress to a Pawnee headress to "fit" in the space thereby disgracing Running Antelope. Running Antelope was a powerful orator, mediator between tribes and policitians and advisor to Sitting Bull. He proposed negotiation over violence.
