Sure you didn't mean the 88 set and not the 90?
GAHHHHH! Dangit! Until you typed that I had actually dismissed the 1988 and 1989 offerings from my memory.
The 1988 Score set was purged because of the cutting error that resulted in every corner of each card from the first print run (which was apparently a trillion cards) to be fuzzed. But it wasn't absolutely forgettable because it was the first fourth-party entry to the mix.
The 1990 set I referred to is simply the worst baseball card set ever produced. It ranks, to me, even below the 1988 and 1989 Donruss sets- which were horrible (as was the 1989 Bowman offering), but still didn't rank as the complete junk the 1990 Score set represents.
