Blue hardcover The Great Gatsby with yellow bookmark

I found a blue hardcover edition of The Great Gatsby this afternoon around 4:15pm outside Square Books on the Oxford Square in downtown Oxford, North Mississippi. It's a Penguin Classics edition, blue cloth cover with gold lettering on the spine, and a bright yellow bookmark sticking out between pages. There's a faint coffee ring on the front cover and a small crease on the bottom corner. Inside, there's a sticky note with the name 'Alex' and a phone number tucked between pages 88 and 89, which should be a good clue for the owner. If this is your book, I'm happy to get it back to you.
