Black Ray-Ban Wayfarer sunglasses with engraved temple

I lost my black Ray-Ban Wayfarer sunglasses yesterday around 3pm. They're in a glossy black plastic frame with gray polarized lenses, the classic Wayfarer shape. Inside the left temple there's a tiny engraving 'RB' and a faint scratch on the lower outer corner of the left lens. I last had them outside the City Museum on 15th Street near Market in downtown St. Louis. I rely on these for driving and reading, and they hold sentimental value because my grandmother gave them to me. If anyone finds them, please leave a note here or message me here—I'd be forever grateful.
