vintage ornate gold plastic / black velvet frames, picture frame trio for photos or prints

Vintage Home Decorators style french country picture frames, rococo gold plastic with black velvet. The plastic is marked USA, paper backings are marked Old Masters. Probably late 60s or early 70s, I think?

These measure about 6 3/4" tall x 5 1/4" wide overall. Oval openings are 3 1/4" x 2 5/8", and it looks simple to insert photos or prints onto the velvet matting from the front. All three of these are in very nice condition, a pretty baroque set.
