There was a comparable situation with Acclaim's Unity 2000. If I remember correctly, they initially produced 2 covers, the regular version and a Dynamic Forces exclusive. But somehow the covers got swapped and the exclusive ended up with the regualr cover, and the regular cover with the exclusive art. And since the regular art was part 1 of a connecting cover, you only had that art if you had the exclusive. So they printed the cover only and shipped it with issue 2, part 2 of the connecting cover. However it was distributed, there *are* graded copies of the cover only:
