River Trading Post offers some of the finest contemporary and historic Native American Arts. This post was the idea of Joe Zeller who worked in an advertising agency and wrote campaigns for many companies including Kraft Foods, Proctor and Gamble, Ford and 7 Up. He also collected native art of the Navajos, Hopi and other tribes. This post was his way of sharing the artistic creations of the native Americans with the world at large. The River Trading Post can also be found in other cities too.
