Native American Sterling Silver Art Glass Screwback Earrings - Thunderbird Front

Dating to the 1950s/1960s or so and STILL bearing the original grease pencil markings on the reverse (design number I suspect), may I offer this pair of Sterling Silver (tested,not marked) screwback earrings. Crafted in a Native American style during the Fred Harvey era of souvenir jewelry, the design to the pieces is that of a Thunderbird set with an oval cab of Art Glass. While not quite Dragon's Breath clear, the glass is certainly the same sort of pink coloring. Fronts measure 1/2" high x 7/16" wide; combined weight of the pair is 3.1 grams. Lovely mellow patina to the silver - if a high shine is desired, all that's needed is a polish.
