Navajo Sand Painting Artist Diane Thomas. Best guess Sun Eagle. I believe this was done in Kirkland Mexico Mid 1960s no later then early 1970s. This is sand painting on a 6 X 6 inch board situated in a Oak Wood Frame 10 X 10 inch. Both frame and sand painting in excellent condition. No soiling. Certificate of Authenticity on back side. A must have.
