Found vintage 1990s baseball cards binder

I found a small black 5x7 binder with clear sleeves stuffed with baseball cards from the early '90s. It's clearly a Topps-era set, with a handful of star rookies peeking through, and the cover shows a bright yellow sticker that reads 'Midwest Stars 1994' along with a blue Sharpie note on the back page. I found it this afternoon around 4:15pm behind the Mall of Abilene on Buffalo Gap Road, near the coffee shop and outdoor seating. It looks like someone put real care into organizing this; I'd hate for it to disappear, so I'm keeping it safe until the owner shows up.
