I am not speaking for Pepis here and I think the question raised is fair and deserves an answer.
But, I did want to mention that cards in cello packs from the early 70s do run in sequence. But, at any moment the sequence can break and another sequence starts. It is definitely possible for the same sequence to occur two times within the same pack. As an example, see this thread over in CU where a member opens up a 1970 Baseball Cello pack. He winds up with duplicates of a couple cards including the card on the bottom of the pack. This makes me believe that, however unlikely, the same card can conceivably show up on both the top and bottom of packs that were distributed in single series cellos like in 1972 football.

BTW - 1970 cello packs purchased from Fritsch are rock solid legitimate. I don't believe that anyone has ever questioned this.
