Got a bunch of this odd set from my trade with Scott Crawford. Apparently the purpose of this set was to have a card for each player in the opening day starting lineup for each team. I'm not sure how this was marketed, it's a bit of an odd concept.
One interesting thing is that some of those pictures must have been taken on that opening day, like these Mariners, who were in Anaheim that day.
Donell Nixon went 0-2.
Dave Valle was 0-4.
Also, some of these photos must have been taken at the same time as the ones used in the 1988 set. On Jody Davis's card this is particularly noticeable.
