Holy cow, this guy is phenomenal. I hope more OA turns up and that eventually it will lead to a book. I can't believe somebody this good has been forgotten.
What a shame that he did so few covers for comics. That's what I hate about the comic book publishers' mentality. It was just an assembly line to them and it didn't matter if the artist was really, really good (like Flanagan). The non-superhero covers to the early DC comics by Flanagan, Flessel, Guardineer, and O'Mealia are some of my favorite graphics of all time.
