The Fleer Sticker Project was a good starting point for the Baseball Quiz cards, but no complete checklist was ever compiled there. I helped supply some of the information for that site.
For example, the Fleer Sticker Project shows 3 cards for the Mets, while I have 5 Mets cards (plus one of those earlier larger cards) as follows:
If there is any interest, I can post pictures of all of these that I know of and then everyone else can pitch in and fill in any additional gaps to try to get closer to a complete checklist for these. Or if someone already has a complete pictorial checklist for these, I'd love to see it.
