Black leather briefcase with brass clasp, found near The Commons

I found a black leather briefcase this afternoon around 2:15pm outside the State Theatre on The Commons in Ithaca. It's a medium-sized case with a brass turn lock and a sturdy leather handle; the leather has a few light scratches and the bottom corner is a bit scuffed. Inside, the charcoal-gray lining has a small pocket with a yellow sticky note bearing the name 'Sophie Nguyen' and a faded coffee ring on a folder—clear signs it's been in use. On the exterior there's a bright green luggage tag with the initial 'S' and a tiny doodle of a coffee cup, which should help the owner spot it, and I figured someone might be worried about it, so I held onto it while I posted this.
