The picture shows a view of this Unusual Old Retro Pair of Ladies Eye Glasses With Case. These are not dated but are believed to be from the 1960s. The frames are mostly clear plastic with a white marbled color on the outer side that makes them look like shell. The lenses are prescription bifocals but without a line. These would make a great conversation piece or theatre prop. They are marked on the inside of the side pieces:
L. EVRARD FRAME FRANCE TWEC
The glasses measure 5-1/4'' wide. The glasses appear to be in mint condition. The silver and gold case has a little wear on the side not pictured. Please note that these are prescription glasses.
