Red Penguin Classics poetry book with blue bookmark

I lost my red Penguin Classics poetry collection yesterday around 3pm along the Pueblo Riverwalk near the Main Street Bridge. It's a 5x7 inch paperback with a creased spine, yellowed pages, and a blue ribbon bookmark peeking out a little past page 120. The back cover has a coffee stain and there's a tiny sticker of a cat on the corner. It was a gift from my grandmother and means a lot to me, so I’d really appreciate getting it back if you happen to spot it around the riverfront benches or near the 4th Street landing. Let me know if you see it—really hoping it turns up soon.
