Lost green-covered copy of 'The Great Gatsby' with handwritten notes and a small coffee stain near the riverfront park in Wilmington.

I lost my favorite book, 'The Great Gatsby', while sitting in a park near the riverfront in Wilmington yesterday. It has a green cover and my handwritten notes on several pages. I've had it for years and would love to get it back. There might be a small coffee stain on the first few pages.
