Those are neat, and I enjoy tracking them as well.
Actually, some have a third version. I don't have all mine scanned/photographed, but there are certainly more interesting and scarcer combinations. For instance, the ROTJ LS have a 2 and 4 pack (as there were 4 issues in the limited series) containing the mewsstand editions, and then there is a third version of 2 packs containing the CPV's. Pictured below are the two packs CPV's with the 75¢ cover prices in a multi-pack display with the shipper behind:
I believe most remain Whitman variants as long as they're sealed and were produced/distributed by Western (some bags are marked as such). Here is an interesting version of the multi-pack containing direct edition (not reprints) of issues 2-4, with no number 1, as was bundled with the Whitman multi-pack with the Suzy Rice Star Wars logo. The last photo is what you find with issues later in the run (starting sometime around issue 20, where they inserted single issues along with other Marvel titles):
Awesome!
That display is amazing. And the original shipper!? Wow.
I also love those Star Wars packs. I still need one more to complete the regular set. I don't have the Canadians though, those are great, and now on my list.
What is a Suzy Rice logo?
