Is there a site policy on how to handle sets like 1988 Donruss/Leaf baseball, which are unique base sets but were both packaged with (identical-looking) puzzle pieces?
The Donruss set has the 21 puzzle cards listed as an insert set, but the Leaf set does not. Was this done deliberately since there is no way to discern, by looking at a puzzle card, with which set it was packaged?
Personally, I prefer to store my puzzle cards with my Leaf base cards. It would be logical if the Leaf set tcdb entry either included the puzzle insert, or some reference to the Donruss one.
BTW, I thought this was an oversight, so I recently added the puzzle insert card checklist to the 1986 Leaf set. I guess it can be deleted if unwanted.
