Navy blue Samsonite suitcase with stickers

I lost my navy blue Samsonite suitcase yesterday afternoon around 3pm near the Grand Arcade on Market Street in Cambridge. It's a medium-sized hard-shell case, about 24 inches tall, with a few scuffs on the corners from travel. The shell is navy blue, and it has a bright red luggage tag with the initials 'P.P.' plus two small stickers—one yellow sun and a panda—that cling to the front. Inside there's a grey hoodie, a pair of brown leather gloves, and a pair of reading glasses in a soft case; the bag has a noticeable dent on the lid and a blue canvas strap that used to be attached to the zipper. It has sentimental value because it was a gift from my grandmother, and I really need it back.
