Re: Artist Editions, another artist that hangs onto his original art is Frank Miller, so maybe some of his Daredevil run is scheduled for this format.

The original Ditko art to all the interior pages of Amazing Fantasy #15 surfaced a couple of years ago, so that could be another Marvel candidate - maybe pad it out with some of those 5-page Ditko shorts, where a collector owns all the pages to a particular story.
