Vintage comic book collection in red binder

I lost my vintage comic book collection yesterday around 3pm near the Meyer Theatre on West College Avenue in Green Bay. The collection is kept in a red faux-leather binder, about 9x12 inches, with a gold embossed title along the spine that reads 'Legends of the Silver Age'. Inside are roughly 28 issues from the 1970s to early 1980s—some with yellowed pages and a small crease on the bottom-right corner, and a tiny green sticker with the initials 'J.R.' on the inside cover. There's also a faint water stain along the back edge. These are irreplaceable collectors items from my grandfather, and I really need to get them back soon.
