Black Samsonite hard-shell suitcase with neon pulls

I lost my black Samsonite hard-shell suitcase yesterday around 3pm outside the Prudential Center on Boylston Street, right near Copley Place. It's a medium-sized case, matte black with scuffed corners, and has neon yellow zipper pulls that make it stand out. There's a bright red leather luggage tag stamped with my initials 'PK' on the top handle, plus a small neon green repair tag on the side. Inside are a few important documents for an upcoming trip and a framed photo of my grandmother—the sentimental stuff that makes me really need it back. If anyone found it, I’d be incredibly grateful to get it back.
