Hey thanks for the comments everyone
I really must get back and finish him off, though a 40K Blood Angels army muscled in a bit!
@Melnibonean: I got a hardback 1st edition of Arkham Asylum, plus Sandman Preludes & Nocturnes TPB from a secondhand shop back in like 1990. That set my comic collection off to a pretty high standard I'd say! Like you, McKean's Joker rendition has stuck with me (haunted me?) to this day.
@baylock: oops, sorry!
s'funny I wasn't going to do a full Batman themed crew but the idea is really growing on me now!
