Blue Penguin Classics hardcover found near Mountain View Café

I found a blue Penguin Classics hardcover this afternoon around 4pm outside Mountain View Café on Pine Street in High Rockies. It's a well-loved copy, the cover shows a coffee stain and the spine is a bit worn, with dog-eared page 128 peeking out. Inside the front cover there's a small ex libris stamp that reads 'A. Fletcher' and a pencil note with the date 'Nov 2019'—looks like a cherished gift or a long-time favorite. I'd love to reunite this with its owner, so if you recognize these details, drop me a line and we can figure out a meetup near the Central Park trailhead.
