First edition blue cloth-bound travel memoir with lighthouse bookmark

Yesterday around 3pm I was lounging along the Newport Bayfront outside Mo's Clam Chowder on SW Bay Blvd, and I must have left my first edition blue cloth-bound travel memoir on a bench. It’s a hardcover with a brass lighthouse bookmark that sticks out between pages. The cover has some scuffs and a small diagonal crease on the back, but the spine is solid. It was a gift from my grandmother and carries a lot of sentimental value, so I really need it back. If someone found it, I'd be forever grateful.
