Ray-Ban Wayfarer glasses, tortoiseshell, blue case

I lost my Ray-Ban Wayfarer glasses yesterday around 3pm near the CSU Bookstore on College Ave in Fort Collins. They’re tortoiseshell with a tiny chip on the lower-left lens, and they live in a blue zippered case with a white Ray-Ban logo. I think I last had them while walking from the library toward College Ave, around the CSU Bookstore area and the bus stop at Laurel Street. They have sentimental value—they were a gift from my grandmother and I’ve worn them every day for years. If someone found them, please drop them off at the CSU Bookstore Lost & Found or at the Fort Collins Public Library; I’d be forever grateful to get them back.
