Revised: 7/25/16
I sent a copy of this to the Smithsonian’s National Museum of the American Indian to find out if they could identify what tribe they may be from. The reply I received reads:
“There are not enough distinctive articles to make a positive tribal identification. However, the purses provide some distinction as coming from the plateau area of the country.”
In my original caption I assumed the plateau was the Colorado Plateau since the negative came from Denver but thanks to Manidoogiizhig and his or her's insightful reply “Perhaps” the plateau area referred to must be the Oregon Plateau.
