What a great estate find!!! 100% original, period 1940's American Optical glasses. Superior construction. These are the best / coolest safety glasses I've ever seen. It is hard to see, but the frames are a super dark, emerald green, as are the side panels and the lenses. The lenses are incredible and can be used as the perfect sunglasses or riding goggles. Ideal for men or women.  Don't miss them.
