1991-92 Coke/Elby's Pittsburgh Penguins Hockey Forum

There seem to be scans of 2 different sets here. I believe the cards that have "1990-91 Stanley cup champions" are from the 1991-92 set but the other ones are from a presumably 1990-91 Coke/Elby Penguins set which includes also players that are not on this set like this Bob Errey:  https://www.ebay.com/itm/354819990643?hash=item529ceb6473:g:VHYAAOSwHE5kIvVr& They are also not blank backed like the 91-92. Anybody have a clue where to find a checklist for the earlier set?
