Vintage Made In USA Blue & Gold Clip Earrings

Good vintage condition, some minor wear and scratches on the metal. The enamel is a much lighter shade of blue than in the photos, probably close to a navy blue. Marked "Made in U.S.A." on a plate on the back of one earring. Made in the 1960's or 1970's. Refer to the photos for size. Offers and bundles welcome.
