Mark,
That box score is very cool. Who hasn't enjoyed a box of Cracker Jack at a game. Sometime between the time I was a kid and today, the toy surprises inside the box went from something really neat to lame stickers.
For a few years in the 90's, mini versions of baseball cards were inserted into boxes. Both Topps and Donruss provided cards, Topps in 1991 and Donruss in 1992.
In 1991, there were two series of 36 cards. Three Orioles were in the set, Cal Ripken Jr in series one and Ben McDonald and Gregg Olson in series two.

In addition to the individual mini cards, 4 in 1 cards have shown up. Most likely uncut sheets being cut up. The 4-1 cards are the same size as a regular baseball card. I just couldn't help myself and started picking up all the Orioles 4-1 variations. I have 18 of what I believe are 19 different, missing only the (Monitor, Clemens, Ripken, Boggs) card. There are 10 different Ripken variations, 6 different McDonald and 4 Olson. One variation contains both McDonald and Olson. I've seen pics of uncut sheets and the repeating patterns of some cards, make some of the 4-1 combos easier to find than others.
