Here's the photos Jay sent me:
Jay was very impressed by BBM's decollation - "The amazing thing was I got NO duplicates". So out of 30 packs of 10 cards, he got 299 unique cards plus one team logo hologram (for the Fighters). What's more, each pack contained the cards in numerical sequence - for example, the cards in a pack were numbered from first to last as "7, 28, 45, 77, 98, 130, 179, 230, 283, 321" while the next would be "6, 27, 44, 76, 97, 129, 178, 229, 282, 320". I've opened boxes from 1992 and 1994 in the past and did not see this behavior (and I'm pretty sure I got duplicates) so I suspect it was only for 1991. I would guess BBM realized pretty quick that something like that would make it possible for someone to predict what cards would be in unopened packs simply by opening the top pack in the stack of packs. (This is assuming that I'm not misunderstanding what Jay sent me and the two example sequences he sent are actual pack sequences and not just something he put together for an example).
Besides the 10 cards, each pack also contained what I think is a promo for the 1991 set - it has a breakdown of the cards in the set (30 cards per team, 23 Leader cards, 10 Nostalgic Stars and the 12 team hologram logos) although it does not mention the 6 checklist cards.
Jay was understandably pretty pleased with his take - for $34.95 (plus free shipping), he picked up about three quarters of BBM's inaugural set.
Thanks for sharing the photos and the information Jay!
