#1 (Malibu, May 1994) is listed here with three versions: standard, ultra limited silver foil, and rear cover variant (don't know why it wasn't called "flip cover variant," but there you go).
The third version may be among the most least-documented of all variant comics. Neither GCD nor Mile High acknowledge its existence. And while CCL does acknowledge its existence, it fails to specify distinguishing characteristics. There isn't an art scan for the rear cover variant, nor is there a difference between credits listed for the primary version and those for the RCV. No one is listing an RCV for sale, and the site lists no past sales for it.Ultraverse Premiere
#2 (flip of Mantra
#10) promoted this issue. It specified the artists involved with both versions. One was by Hoang Nguyen and Terry Austin. The other was by Nguyen and Bob Downs. Malibu didn't specify a primary and a secondary, nor that either would be more common than the other. Perhaps the flip cover that appears on the ultra limited silver foil version, or on the newsstand version (if one is ever found), ought to be considered the primary (oh, but what if there are two versions of those, as well?).
My copy has the Downs-inked flip cover. I didn't know until recently that I ought to be looking for a second version.
Just now, by looking on eBay, I found a scan of the Nguyen-Austin cover. Here it is (subject to disappearance after the associated auction):
And here is a shot of the Nguyen-Downs cover (also subject to disappearance):
So, my questions are:
1) What cover(s) are on the flip of the ultra limited silver foil version?
2) What cover(s) are on the flip of the newsstand edition?
3) Is there any basis to consider either version more common than the other?
4) Which flip cover is CCL's primary? Which is the RCV?
