This is a pair of aluminum framed cat's eye shape women's trifocals. They scream 1950s.  They are finely embellishment in silver incising with red, gold, and blue rhinestones. The basic frame is black aluminum with chrome components. They are extremely strong with many years of life left and could easily be fitted with modern lenses. The inside of the bridge is marked " 1/10  12 K ". The frame is 5" in width and the temples are 4 1/4" (marked). I do not know the maker nor do I know if the name on the case is the maker. If you know the maker kindly let me know. Please view photos and email questions.
