Black leather Briggs & Riley briefcase with brass hardware

I was in Jackson, Wyoming yesterday around 3pm after meeting a client, and I think I left my black Briggs & Riley briefcase near the Million Dollar Cowboy Bar on Broadway. It's a medium-sized black leather case with brass hardware and a small scratch along the bottom edge; the red lining peeks out when you open it. Inside there's a faded sticker with the initials 'PW' on the inner pocket and a yellow sticky note that says 'Invoice Q3'—please don’t rummage through the files, I just want the case back. This briefcase holds important client documents for my small design business, and I really need it back; it also was a gift from my mentor, so it means a lot to me.
