Gray Ray-Ban Wayfarer sunglasses with initials PP

I lost my gray Ray-Ban Wayfarer sunglasses yesterday around 3pm near the Arc of Dreams sculpture in Falls Park, downtown Sioux Falls. The frame is gray matte plastic with dark lenses, and it's in decent shape except for a tiny scratch on the right lens. Inside the left temple there's an engraving with the initials PP. They were a gift from my sister and I really rely on them for driving and daily work, so I'd be incredibly grateful to get them back. If you found them, message me here and we can arrange a pickup.
