A fabulous pair of retro cat eye eyeglass frames with lovely detail. They have tiny gold diamonds in each outer corner on front & on sides, & the nose piece is delicately patterned. The shaped upper frame & arms are black & the lower part of the frames is gold. We think the gold-toned metal may be genuine gold; the black portions may be bakelite. These frames include the original bifocal prescription lens. There are no markings inside arms.
