When we lived in Arizona I volunteered for the Native American Tucson fair. Each artist contributed a piece of their work to be auctioned off and the money raised was to support the fair and or Native American artists. This was an invitation fair. You would see jewelry in silver and gold plus basket weaving etc. and a lot of the natives had a child with them that was being taught the business
This is just one piece that I purchased through buying a ticket for the raffles it was a lot of fun and you also got to meet the artisans close up and talk with them. The certificate of authenticity came along with the piece that you won
