Not on most people's radar, I know, but if there has been comic I've wanted original art from, it was ROBIN: JOKER'S WILD. It was one of those comics that just stick with me as a kid and it remains a favorite.
Anyhow, I saw a great page up for sale, and while not the original line art from Tom Lyle, and it IS the original hand colored art from Adrienne Roy. It's a great page set up and pops in person.
Not a Kirby, Miller or someone else, but for me, I've posted here about wanting a page from this mini almost as long as I've been a member here.
