Blue binder with 1980s baseball cards

I lost my blue vinyl binder full of vintage 1980s baseball cards yesterday around 3pm near the State Theatre on 10th Street in downtown Modesto. The binder is small, about the size of a paperback, with a white star sticker on the front and a few cards peeking out from the sleeve. Inside are three Topps cards from the mid-80s and some loose cards; the binder has sentimental value because it was a gift from my grandfather. If you found it, I’d really appreciate getting it back—this collection means a lot to me and I’d be forever grateful.
