Well-worn The Great Gatsby paperback with coffee stain

I lost my well-worn The Great Gatsby paperback yesterday around 3pm. It's the greenish paperback edition with a cracked spine, dog-eared pages, and a coffee stain on the back cover. It was a gift from my grandmother, so it means a lot to me and I’m really hoping to get it back. I last had it while sitting on a bench near the Centennial Park gazebo along the Davenport riverfront, not far from the Mississippi River walk. Inside the front cover there's a small doodle of a coffee cup on page 42 and a blue ribbon bookmark peeking out—if you found it, please drop me a line.
