I regularly check eBay for Awesome items, just to see what might pop up and came across this interesting little tidbit. American Entertainment, which regularly supplied variant covers and special versions of Awesome books sent this out to people who preordered Judgment Day: Final Judgment and Agent America:
I discussed the Fighting American/Agent America stuff here, but in summary, Liefeld left Marvel and decided to publish some leftover Captain America pages he made as a series called Agent America. Marvel raised a fuss and Liefeld licensed the character of Fighting American from Kirby/Simon and the lawsuit got settled.
It makes sense that they'd give away the preview for Agent America at this point since they were no longer going to publish Agent America.
Another twist is it might explain why there are these variants for Judgment Day Alpha that are almost exactly the same, except one features Fighting America and one features Die Hard in the same location/pose.
After a several-month delay, Judgment Day: Final Justice did come out, as did three series of Fighting American.
