Seems to be a meme whose time has come.
From The Village Voice: Features: American Gods by R.C. Baker:
Alex Ross, one of America's preeminent comic-book artists, recounts the genesis of his 1997 Uncle Sam comic. "[Writer] Steve Darnall and I both felt that our culture was at a crossroads of its own selfishness," he says from his studio near Chicago. "The American spirit was at a very low ebb," he adds, pointing to the profligate Clinton economic boom as "a blinding factor."Asked to do a cover painting for this issue of the Voice—a riff on the finger-flipping patriot deemed too provocative for the hardcover edition of Uncle Sam—the chronically overscheduled Ross hesitates, then chuckles. "If you'd asked for anything else, I'd have had to say no. But I've wanted to get that one out there for a long time."
"Uncle Sam represents the government," Ross says, "and our current government is giving us the finger. But you can turn that around and see the true spirit of the nation giving it back to a government that is telling its citizens, 'We know what's best—don't question us.' That finger is definitely a fuck-you back at this government."
Noticed a poster at Chicago Comics yesterday, walking from Pick Me Up to the El station on Belmont, advertising "a joint signing [by Alex Ross and Chip Kidd] for the release of JLA - LIBERTY & JUSTICE and MYTHOLOGY: THE DC COMICS ART OF ALEX ROSS" on Saturday, December 13th, 3 to 6 PM.
Pretty sure I got the (oversized, gorgeous) Superman book he did, but not the other. . . two, at this point?
Update One: By way of The Comics Journal: ˇJournalista!:, coverage of another Alex Ross signing in the Toledo Blade.
Update Two: The Crew #7 and the first issue of Kyle Baker's Plastic Man are in shops even as you read this.
As is Superman/Thundercats.
Yes, you read that right. Superman/Thundercats.
Perhaps you skimmed that the first few times.
SUPERMAN/THUNDERCATS
The Earth is doomed.

Superman/Thundercats??? NO WAY! ROCK ON! I'm so excited!
You're utterly adorable, you know that?
And, from your nick, playing for the other team.
Why does this always happen to me?
That was a rhetorical question. I wasn't really expecting an answer. Yes, Michelle, I'm looking at you.
Well, vaguely towards Indianapolis, anyway.
Or Louisville.
Or that little town you come from named, "Fresh off kicking a 'Baby Got Back'-listening-Negro's fool behind." Sorry if I'm making you homesick.
