Rhett YeakleyFrom what I understand is that all high # cards (including Joe Jackson) will always have the Superman ad on back, there are a couple different taglines but all the high #'s will have a Superman ad. The variation that REA is talking about is only found on cards #123-180 (The Mid-#'s of the set), these cards can be found with the conventional baseball ad on bottom or the Superman ad.
I had not really noticed that they were all that much harder to find than the regular baseball ad back (but you do see less of the Supermans), but admittedly I have never tried to make a set of them either.
