Black leather briefcase with initials AR

I lost my black leather briefcase yesterday around 3pm near Fountain Square Park in downtown Bowling Green. It's about 14 inches wide, 2 inches thick, with a soft, worn feel and a gold-toned zipper; the bottom-right corner has a small scuff and the top handle's stitching shows a tiny fray. Inside there's a navy notebook with my initials 'A.R.' on the first page, a blue USB-C cable, and several work documents. It really matters to me—it's sentimental since it holds notes from my late grandfather.
