Vintage 50s Cateye Glasses American Optical

Vintage fifties reading glasses are by American Optical.  They are cateye bifocal glasses.  The center of the frame is marked 1/10 12KGF for gold filled metal.  The temple length of glasses measures 5 1/4".

The glasses have minor wear & are in good condition.  I have polished hinge with Wright's Silver Cream & removed verdigris.  Blue eyeglass case is not included.
