after reading the trivia info "
- Cards marked as SP (short printed) from 648-660 are more difficult to find than the other 13 SP's in the lower 600s. These 26 cards listed as SP were apparently pulled from the printing sheet to make room for the 26 Bonus MVP inserts. Six of the checklist cards were done two different ways to reflect the inclusion or exclusion of the Bonus MVP cards in the wax packs."
I thought these might qualify for SSP for a moment reading that and then I came back to reality.. However I would (as everyone else) love to know a print run of this set and how many of these where printed.
However, after 35 years alot of these cards were damaged, destroyed, thrown away. I still hear someone is printing 90 Donruss 😂 but ... Still I see 1988 Donruss Boxes at shows so supply is still hanging around
