Lost well-worn paperback copy of 'The Great Gatsby' left on a bench in Riverside Park, Sioux City.

I recently lost my beloved copy of 'The Great Gatsby' while sitting in Riverside Park in Sioux City. I remember taking it out to read, and when I left the park, I accidentally left it on the bench. It's a well-worn paperback edition with my name written inside the cover. I'm really hoping to get it back, as it has sentimental value to me.
