Candy pink and lime or neon green plastic drops dangle on goldtone links attached to a pink round disc.  On the front of one of the discs there are some scratches. The earrings measure 2 1/2" long. They are marked on the stem: Wingback Pat.2414382.  The patent dates to January 1947 and was made by Judith McCann. Wingback earrings are known to be difficult to master, but once understood they are extremely easy to wear and are particulary good for heavier earrings that might otherwise tug too hard on the earlobe.  The wing part and the stem should not be engaged. The wing part slips over the thinnest part of the ear edge in the front, the stem stays behind the ear.  Then slip the earring down so that the wing part sits on the inside top of the earlobe and the stem is behind the ear!
