Blue Penguin Classics poetry collection, slightly bent spine

I'm posting this in the Books & Magazines category for Southwest Michigan because I lost it yesterday around 3pm in downtown Kalamazoo, near Bronson Park on West Michigan Avenue. It's a navy blue Penguin Classics hardcover, about 260 pages, with a slightly bent spine and worn corners. There's a red ribbon bookmark sticking out and a small coffee stain on the first page, plus a white library sticker on the inside back cover with the number 402. This book was a gift from my grandmother and holds a lot of sentimental value for me; I'd be grateful to get it back if anyone finds it.
