Black leather briefcase found near Bienville Square

I found a black leather briefcase this afternoon around 2:10pm on Dauphin Street outside a cafe near Bienville Square in downtown Mobile. It's a sturdy 14-inch case with a worn leather handle and brass hardware that still shines. Inside there’s a navy notebook, a white USB-C charger, and a red leather luggage tag with the initials 'A.Y.' The lining has a small coffee stain in the bottom corner, and the label on the inside reads 'Briggs & Riley'—the tag itself is a bit frayed. It seems well cared for, which makes me think it belongs to someone who travels a lot. If this is yours, tell me a detail about the contents to prove ownership.
