This frame has definitely been much loved in its time! There are signs of wear on the temples and there is a mark on the right lens where the left arm touches it when shut (a common problem with frames this size).
The frame was probably made in France, as it has a lot of “similarities” to certain Yves St Laurent sunglasses.
These glasses are not suitable for prescription lenses, but if you are looking for the correct accessory to go with your vintage outfit, then this is the frame! At this price you can’t go wrong!
