Black leather briefcase with initials AH found

I found a black leather Samsonite briefcase this afternoon around 3:15pm in the parking lot behind Oakwood Mall on Clairemont Avenue in Eau Claire. It's a medium-size case with a brass zipper and a small scuff on the bottom corner; outside is a leather tag embossed with the initials AH. Inside there's a blue notebook labeled 'Q3 Proposals' and a red fountain pen clipped to the inner pocket. I'd really like to see it back with its owner soon, since I know it probably holds important documents.
