The first two are a compare and contrast.
Pete O'Brien (card # 259)
The 1991 Bowman set features 704 cards compared to 528 cards in the 1990 issue. The cards imitate the 1953 Bowman style. Special Rod Carew cards and gold foil stamped cards are included. The set is numbered by teams. Like the 1989 and 1990 issues, the card backs feature a breakdown of performance against each other’s team in the league.
I guess that the little shiny crossed bats near Julio's head would be the "gold foil stamp". I'm not quite sure what it means, but I've seen some references to SLUG or SLUGGER.
Julio Franco (card # 368)
Kirby's got a BIG bat. I'm guessing that there is some sort of MLB rule about the size of a bat. And I'm right...
MLB Official Rule 1.10
(a) The bat shall be a smooth, round stick not more than 2 3/4 inches in diameter at the thickest part and not more than 42 inches in length. The bat shall be one piece of solid wood.
Kirby Puckett (card # 200)
The following card is designed solely to make Night Owl's head hurt...
Eric Young (card # 730)
