Vintage Topps baseball card binder lost

I lost my vintage Topps baseball card binder yesterday around 3pm near the Fargo Theatre on Broadway. It's a black vinyl 9x11 binder, with a red Topps sticker on the spine and a coffee stain on the front corner. Inside, there’s a mostly complete 1980s set and a small pocket with a handwritten checklist that starts with 'Rookie: Ripken' and 'Sanders.' The binder means a lot to me because it's part of my late grandfather's collection, and I really need to get it back. If you found it, please text or email me and I can describe more specifics to confirm ownership.
