That is an interesting buckle. it is a Zuni piece and the background is tortoise shell which was banned in the early 1970s. I think of Elliot Qualo when I see that buckle, but I have never seen a piece where he uses a kachina and raised above the background. It is also interesting the inlay marking on the backside. If you could identify the maker you might be able to get a premium, like it is I would think around $1000 - $1200. The bracelet is Navajo from the same time period, $225 - $300. Thanks for sharing.
