VINTAGE Silver Cat Screw Back Earrings Crazy Cat Ladies 1950s Mid Century

Reposhing this item I purchased from @sarahjayne713. Loved it, but ready to rotate for something new. Sold as is! Size is a tiny bit larger than a dime. Part of an estate lot. Untested silver. Unmarked. Not sure. Could be sterling. Has some tarnish. Screw backs are not silver. See all photos. Cool unique earrings Thanks!
