Lost black leather backpack with a small scratch and a miniature guitar keychain on the zipper, containing a laptop and personal items.

I lost my black leather backpack while walking through the downtown area of Columbia on Main Street around 3 PM yesterday. It has my laptop inside along with some personal items, including a book I'm really fond of. The backpack has a small scratch on the front, and there’s a keychain with a miniature guitar attached to the zipper. If anyone has seen it or finds it, I’d greatly appreciate it!
