Gray 21-inch Samsonite carry-on, sentimental loss

Hey, I’m pretty bummed—I lost my gray 21-inch Samsonite carry-on in Baltimore yesterday around 3pm. It was last seen near the Inner Harbor by the National Aquarium, maybe by a bench along the promenade. The hard-shell bag is matte gray with a couple of scuffs on the corner and a red heart sticker on the top lid, plus a blue airline tag with the initials AK. Inside I had a small travel journal and a photo album; it’s really valuable to me because it was a gift from my grandmother and holds a lot of memories. If anyone found it, drop a message here—I’d be so grateful to get it back.
