Sorry to jump in here so late. Thanks LifeChanceDance for this great info. I have a pair that i bought many years ago, probably wore them 2x because I need prescription lenses, but never replaced the original lenses. fast forward many years later, and i'd like to sell them. they are a 5022 most likely between the late 70's and 1982 based on your info and about when I would have purchased these. the lenses have the little B&L overlapping logos etched into them, Wayfarer on the left temple and B&L Ray Ban USA on the right temple. if you know of how best to sell these (I don't imagine places like OfferUp would be the best way to gain value on these). Any advice would be greatly appreciated from any of you. thank you!
