Vintage red stamp album with 1950s stamps

I lost my vintage red stamp album from the 1950s yesterday around 4pm near the Utica Public Library on Genesee Street. It's a red binder with a black spine, about 9 by 7 inches, filled with mint-condition stamps from the '50s and '60s, including a few rare Canadian issues, all held in clear sleeves. There's a small coffee stain on the top left corner and a handwritten label 'JP' on the first page. It was a gift from my grandfather and holds a lot of sentimental value—I really need to get it back.
