Lost & found collectors items in Western Maryland

Lost stamps in Western Maryland, help please

I lost my stamp collection, and I’m hoping it turns up. My name is Maya Collins, and last Friday at 5:30 PM I realized a few stamps were missing from the album I keep on the shelf by the window at the Washington County Library, downtown Hagerstown. The set includes a red 1910 commemorative and a small strip of green issues, worn from years of handling. I last touched the album near the window by the cafe and then walked out toward the C&O Canal Trail. These stamps were my grandfather's and carry memories of summers spent along the canal. I’m trying not to panic, but I’d be grateful for any hint through the site about their whereabouts.
