These are vintage American Optical AO 52/20 men's aviator pilot sunglasses. The frame is gold and in overall good condition for its age. I am not sure what era these are from as I acquired them year ago from a family friend. They have been in storage more years than i can remember. The lenses are dark gray and made of real glass, also made in the United States. Please review all photos as they are a part of the items description and let me know if you have any questions, thanks for looking.
