These photographs of the old Dakota Territory are fascinating. I’m not sure where these pictures originally came from. In many ways, they look like the Edward Curtis photos that were taken between 1885 and 1930, but some appear to have been taken too early to be his work. http://en.wikipedia.org/wiki/Edward_S._Curtis
The photo above of the Cheyenne Indians looks like it is a posed photo, perhaps for visitors. You can see what looks like pricing on the placard at the bottom of the picture. Did you pay to have your photo taken with the Indians?

Blankets were such an integral part of Indian life. The patterns are beautiful. I wish we could see color. Notice that the Indian on horseback has no saddle.
