And Klaus Janson, I believe

Yes, good call. I stopped reading comics not long after Klaus took over for Miller with Daredevil and was always disappointed with his drawing style, which was similar to Miller's but looser in an unsatisfying way. Did he go on to do interesting work?

Not that I know of. He did Punisher: War Zone at first and it was good at times. For some reason I remember issue 2 as being really good.

Also he and Miller parted ways at some point during The Dark Knight Returns. I think part way through issue 3. So the last issue actually was inked by Frank Miller himself.
