Red paperback poetry collection lost near Guthrie Green, Tulsa

I lost my red paperback poetry collection yesterday around 3pm near Guthrie Green in the Brady Arts District, Tulsa. It's a compact 120-page book, in decent condition, with a blue ribbon bookmark sticking out of the top. The cover has a hand-drawn heart in the corner and there's a small coffee stain on the back cover; a couple of pages are dog-eared. It was a gift from my sister and holds sentimental value, I'd really need it back.
