Black leather briefcase with red strap, initials PR

I lost my black leather briefcase yesterday around 3pm on the Seaside Heights boardwalk near the Casino Pier. It's about 16 inches long, with a detachable red nylon shoulder strap and brass zipper pulls, a bit worn at the corners. Inside there's a lime-green Post-it with my contact and the latch is engraved with my initials 'PR' for a quick ID. It also holds a photo of my grandma and some work files—it's sentimental and I really need it back.
