Has anyone tried emailing the guy to ask him about it? Maybe he'll surprise you and actually tell you about it!
Rob, I'd rather armchair quarterback, speculate a bit, and then consider launching a smear campaign, because it's a lot more fun than asking.
But seriously, considering this description,
Up for auction is a 1979 wacky packages sticker encased in plastic with a strange outer boarder. The border is fairly heavy and appears to be light cardboard. Its a little bent around where the cardboard touches the plastic case. The artwork looks like it was done by one of the original wacky pack artists, but I cant find any info on this. he probably doesn't have much info to offer, but it might be interesting to find out where he got it, which might be a clue to it's origin / creation.
