Autographed Penguin Classics poetry paperback

I lost my autographed Penguin Classics poetry paperback yesterday around 3pm outside the Crandall Park entrance on Warren Street in Glens Falls. It's a small 6x9 inch paperback with a bright blue cover and a silver title that's slightly worn. Inside, there's a blue bookmark with the initials 'AP' and a pencil note on the first page that says 'for Sam'. It means a lot to me because it was a gift from my aunt, and it's got sentimental value. If anyone found it, I would really appreciate returning it—I'm really hoping to get it back.
