Navy blue US passport, lost in Frederick

I lost my navy blue US passport book yesterday around 3pm after I set my bag down on a bench outside the Frederick Market on Market Street near City Hall. It's the standard blue passport with the gold eagle crest, and you can spot it by the small coffee stain on the back cover and a tiny sun doodle I drew on the inside cover next to my name tag. The book is a bit worn from travel, with a few creases along the spine and a minor bend on the lower edge. If anyone found it, please let me know — it's essential for my trip and has a lot of sentimental value.
