Kellogg's 1991-92 Hockey Card Packs

I like the unopened packs of Kellogg's cards from 1991-92.  There is just one big problem.  The packs have two cards with both of the fronts being visible through the clear cellophane.  Both cards display the Score logo and there is no mention of Kellogg's except for the last card - Cornelius Rooster.

I added pictures of the front and back of the Patrick Roy card in this post - 1991-92 Kellogg's Hockey Cards - Produced by Score.  The back does have the Kellogg's name on it. 

Here is the checklist.

1	Patrick Roy
2	Rick Tocchet
3	Wendel Clark
4	Mike Modano
5	Jeremy Roenick
6	Pierre Turgeon
7	Kevin Hatcher
8	Brian Leetch
9	Mark Recchi
10	Andy Moog
11	Kevin Dineen
12	Joe Sakic
13	John MacLean
14	Steve Yzerman
15	Pat LaFontaine
16	Al MacInnis
17	Petr Klima
18	Ed Olczyk
19	Doug Wilson
20	Trevor Linden
21	Brett Hull
22	Rob Blake
23	Dave Ellett
24	Cornelius Rooster

If someone found these packs they would have no idea that they came from Kellogg's. 

Now that I have a bunch of them in unopened packs I guess that I will attempt to collect the entire set in unopened packs.  It is a cheap, although not easy to find set, so should I get picky and find each player appearing on the front of a pack?

If I am locked in my house for a long time with time on my hands should I search for all of the front/back combinations.  Are all combinations possible?  All combinations could be all 24 cards with 23 different backs.  Ugh.  That is not going to happen unless I find an entire box full of that stuff.  That is more likely with the Kellogg's basketball cards since they are really, really affordable.
