Blue hardcover Boston travel guide, lobster doodle note

I lost my blue hardcover travel guide to Boston yesterday around 3pm near the Boston Public Library in Copley Square. It's a sturdy 5x8 inch book with a slightly scuffed blue cloth cover and the title 'Boston Walks' in white letters. Inside there are color maps, a few dog-eared pages, and a yellow sticky note with a small lobster doodle. It has sentimental value because I was planning a weekend self-guided tour of the city, and I drew little notes for each stop. If someone found it, I’d really appreciate it if it turned up near the library steps or along Boylston Street by the Prudential Center. You can reach me via email at [email protected].
