Wendy, I don't have an answer for your question but, if no one else
in Orchid answers, here are two places I would turn to:
The magazine, "Arizona Highways", published by the Arizona Dept.
of Highways, who periodically have published collector's
editions entirely devoted to outstanding Native American
The Indian Jewelers Supply Co., headquartered in Gallup, N.M. While
IJS services the general jewelry trade, it is located in an area
noted for Native American artists. They would likely know if such a
list or index exists.
Hope this helps,
