Score debuted 1988 with a set with 100% action shots. What a great idea! They also inserted into packs and factory sets these Magic Motion cards:
The magic motion part on the front is pretty much useless but the back contains trivia, highlights, and baseball history.
1988: Do You Remember? (Canuck beat ya to it, aye?)
1989: A Year to Remember (sold to wickedortega for $0)
1990: The MVPs (Chris D'Orso now owns these)
1991: World Series Trivia
All sets claimed!
