Now this convention poster doesn’t look like Curt Swan to me, but it’s a terrific image of Superman nevertheless. It’s like Swan somehow did a different version of the Man of Steel fromn the one he normnally did. Anyway, no idea what convention this poster is from.
Check the super-sized version.
And I usually associate Ron Smith with Judge Dredd, but he does an incredible Anderson too. This is from 2000AD Prog 718.
Go look at the larger version. Drok!
