This inlaid Rainbow Dancer pin dates from ca. the 2nd quarter of the 20th century. It may have originated in one of the workshops (such as Maisel, Hurd, Tammen, etc.) which employed Native American artists to create jewelry for the Fred Harvey Company stores and other outlets.
Of the inlaid vintage Zuni pins we have as of March 2020, this is the largest.
1 3/8 inches high x 1 1/8 inches wide; RAE and TEX are hand engraved on the back of the pin.
