Penguin Classics paperback of Invisible Cities

I lost my Penguin Classics paperback of Italo Calvino's Invisible Cities yesterday around 3pm, outside the Star Café on Main Street in St George. It's an orange cover with a red spine, about 8 by 5 inches, and it has a small crease on the lower-right corner and a faint coffee stain on the back. There's a tiny pencil lighthouse doodle on the inside front page and a blue ribbon bookmark peeking out a bit. It was a gift from my grandmother and is packed with notes for my thesis, so it means a lot to me; if anyone found it, I'd be incredibly grateful to have it back at [email protected].
