Blue hardcover atlas with green bookmark

I found this blue hardcover atlas this afternoon around 4:15 PM in the parking lot behind the downtown public library on Main Street in Saginaw. It's a National Geographic World Atlas, big and heavy, about 11 by 9 inches, with a cracked spine but all the pages are intact. Inside the front cover someone wrote 'A. Morales' in pencil and there’s a yellow bookmark ribbon sticking out between pages 40 and 41. There's a coffee stain on the back cover, and the edges are a bit worn from travel. If you recognize these details, message me here and I’ll hold onto it for you.
