Slash Maraud would be released as Vertigo today, but I don't think it's good enough to be reprinted.

Denny O'Neil and Rick Maygar's The Question ongoing series from the late 80's was mature, entertaining, and retained a level of quality through all 36 issues (except for the one with The Riddler, where the guest artist flops... I can't think of anything other issue I didn't like). I think it didn't get cancelled, O'Neil ended it because he wanted to try other things, which is a good thing. So, the last arc is great gives closure to the story, and doesn't just end it abruptly when the series has become mediocre like with other comics. I doubt it'll get reprinted, though, cause the issues are selling for like a buck each in milehigh, so it's not a very popular comic.
