Have you checked out all of DC's desktops patterns lately?
That's where I found this image and I've also got the Gene Ha Authority piece on my computer right now. Sweet stuff. And they've got a lot of different ones from WildStorm, Vertigo and DC too.
Oh, and the McFarlane cover's a 1/10 variant. Plus, there's another pencil variant of Jim's cover limited to 1/50 copies too.
Just two more days to WildCats #1...
