Blue hardcover travel memoir with yellow ribbon bookmark

I lost my blue hardcover travel memoir yesterday around 3pm near Bryant Park, the 42nd Street entrance between 5th and 6th Avenues. The cover is a bit worn and the back has a small green circular sticker with NY written on it, plus a tiny pencil doodle of a subway car on page 92. Inside, there's a yellow ribbon bookmark marking that page, and a few pencil notes about urban walks I took last spring. It means a lot to me because it was a gift from my grandmother who passed away last year, and I really need it back. If you find it, reach me at [email protected].
