The game got the best of my curiosity and so I decided to buy the entire set.
This is what the original package looks like. The box calls the cards "rare baseball photo cards." It's been 26 years since the set was released and you can buy most of the cards for 18¢ each at Sportlots, so I wouldn't consider them to be "rare."
The game was approved by the players association but it must have had MLB's blessing too since there are logos showing on the cards. The game also had the involvement of Little League Baseball. Nothing like using the kids to make a buck!
I seems like a poor mans version of Trivial Pursuit. But I'd rather have cards than slices of a plastic pie and with Baseball Wit you don't have to worry about...
