56-20-145 Mainstreet 302  Unisex 1970’s bold acetate aviators.

Unisex 1980’s bold acetate aviators.
Riveted barrel hinges are the MOST desirable type of hinge,  
Mainstreet made them this way up til about the 1980's and then went to the standard flat heat set hinges which don't last as long.

Very sturdy frame, 1980’s pre-owned in excellent condition.  Lenses are prescription and I can remove or leave them, up to you. Let me know in your order when you purchase. I will remove them if I don't hear from you.
Polished, straightened and ready for your own RX.
