Courtney Crumrin creator Ted Naifeh has a gallery up on his website showcasing sketches and sample pages that feature the Caped Crusader and related characters.
“It’s clear to me that anyone doing the Joker ought to start, like Bob Kane and Bill Finger did, with The Man Who Laughs,” Naifeh says in the comments field of the gallery. “As you may already know, by big introduction to comics was DKR, and the Joker was completely amazing in that (until book 3, anyway). So yeah, I really want to do a Joker that doesn’t smile until it really counts. Like so many other things, they did a great job of that in TDK. Boy, I tell ya. That film was like experiencing DKR all over again.”
