Black 28” Samsonite suitcase with red tag

I lost my black 28-inch Samsonite suitcase yesterday around 3pm after I stepped off the metro at Monastiraki and wandered toward Ermou Street. It's a sturdy hard-shell case with a few scuffs on the bottom edge and a bright red fabric luggage tag with my initials 'S.D.' on the handle. One corner shows a small dent, and the zipper pull is slightly bent from travel. Inside, I had my travel documents, a printed itinerary, and a faded photo of my grandmother—things I can’t replace. If you found it somewhere near Monastiraki or Ermou, please reach out; I really need it back.
