There's also several versions of Kirby's original run:
1) the original 1970-1972 runs
2) the 1985 NEW GODS 6-issue Baxter reprint (and HUNGER DOGS conclusion)
3) the black & white trades of NEW GODS, FOREVER PEOPLE and MISTER MIRACLE in 1999-2000. and a 2-volume color JIMMY OLSEN trade
set released in 2002-2003
4) and the 4-volume hardcover set of JACK KIRBY'S FOURTH WORLD in the last few years.
It's nice to have these issues in any form, but I think they've screwed up each of these reprintings, and I'm still waiting for a
definitive collected version.
My ideal would be an EC-library like boxed set, with each series in a separate hardcover.
