Leather briefcase with initials found near Syntagma

I found a black leather briefcase this afternoon around 3pm outside the Acropolis Museum on Dionysiou Areopagitou, Athens. It’s about 14 inches wide, with a brass clasp and a worn leather handle. The burgundy interior is neat, and in the front pocket sits a small photo and a USB drive labeled 'NP-2024'. A brass plate on the outside is engraved with the initials 'KD'; there’s a light coffee stain on the bottom corner that gives it character. If it’s yours, verify with the initials, the burgundy lining, and the USB drive contents. I’ll keep it safe and arrange pickup through the app for you to confirm.
