I am going to go out on a limb here and say he is from the Tohono O'odham Nation and not from the Yaqui tribe. I will just tell them Jim Follis told me so! God Help me if I am wrong! The Tohono O'odham Nation owns both Desert Diamond Casinos and the Pasqua Yaqui Tribe owns the Sol Casinos... Casino del Sol & Casino of the Sun. Thanks for your help on this chip Rich with the info with the card picture. If all goes as planned, a nice framed LARGE picture of this chip will be hanging in the Desert Diamond Casino Administration office soon.
