Black leather briefcase with brass hardware

I lost my black leather briefcase yesterday around 3pm. It was left on Bayfront Drive near the Van Wezel Performing Arts Center in Sarasota after a quick meeting. The bag is black full-grain leather with brass hardware, about the size of a 15-inch laptop bag, and it has a small scuff on the lower front corner. A red leather luggage tag is attached to the top handle, and there’s a tiny scratch on the front. Inside there’s my slim laptop sleeve, a manila folder with client notes, and a blue Post-it with my initials MK in the pocket. It also contains a family photo I really need back.
