I have two comments about this set.
Card AD1 is listed on Beckett as an advertising panel with no number printed on the front or back. (They have an image) Beckett also considers it to be card #AD1 but it seems like a NNO to me. Should we adjust this?
Is the checklist considered the 121st card of the base set or an insert card? If it is considered the 121st card, then we should list it with the other 120 cards like the checklists in 1981 and 1982 Donruss baseball. If it is considered an insert card, then we should change the set size to 120.
