Vintage Renoir Copper Fish Clip Earrings

Renoir copper fish earrings shout Mid-Century Modern! These clip-on earrings are marked, "Renoir" on the backs. They are made of copper with large black eyes and are in good condition save for some normal wear and a bit of tarnish. This is the first time I've seen this design, and they are quite hard to find. Made in the 1950's.
