Lost black leather wallet containing driver's license, credit cards, cash, and a family photo at Riverside Park bench in Wichita.

I believe I left my black leather wallet on the bench at Riverside Park in Wichita yesterday afternoon while I was out for a walk. Inside it has my driver's license, a few credit cards, and some cash. It also has a small photo of my family tucked in one of the card slots. I'm really hoping to get it back, as it has sentimental value as well as important information.
