Ray-Ban Wayfarer sunglasses, black frame

I lost my Ray-Ban Wayfarer sunglasses yesterday around 3pm near the Cambridge Public Library on West Wheeling Ave. They are black plastic frames, medium size; one lens has a tiny scratch near the bottom and there is a small nick on the left temple. The silver RB logo sits on the temples, easy to spot. They came with a blue microfiber case that I kept in my bag, and I have been feeling off without them all day. They were a gift from my grandmother and have sentimental value, so I would really appreciate getting them back. If you found them, please message me and we can arrange a meetup near the library or a nearby cafe.
