Just finished reading TwoMorrow's "The Krypton Chronicles" (nice job by Michael Eury there ...)
I believe Mr. Eury himself suggested, in his interview with the great Neal Adams, a collected "Neal Adams' Superman".
We know that Mr. Adams is probably better known for his Batman work but it would be a kick in the head to see his Superman work collected in one place.
Of course, I'm sure they couldn't include probably one of the best comic books of all time, "Superman vs Ali", due to legalities over rights. *sigh*
