Blue Penguin Classics poetry collection with gold lettering

I lost my blue Penguin Classics poetry collection yesterday around 3pm near the Huntsville Public Library on Clinton Avenue. It's a small paperback, about 5 inches tall, with a faded blue cover and gold lettering; the spine is creased and there's a dog-eared corner on page 78. Inside, there are margin notes in my own handwriting and a green sticker with the initials PK on the back flap. It means a lot to me—it's a gift from my grandmother and holds sentimental value, so I'd really appreciate getting it back.
