This is a Carlson Indian doll; her number is 12-2. She has the older style paper tag on her leg. According to the Carlson Dolls catalog, number 12-2 is the Oglala Princess, though the costume in the catalog (on the right) is quite different.

I purchased this doll at an antique show in Colorado in October 2009, with the stand. I do not know if this stand is original for this doll or not.

This the the Oglala Princess as she appears in the catalog. I believe the doll I have is older and most likely pre-dates this catalog.
