You and me both on 70s Batman...I have a lot of it, the best stuff, but it is a veritable labyrinth of various trades and single issues. I hate Neal Adams recolorings and retouchings, refuse to own them, so yea...that makes it all even more difficult.
I'm gonna get that New Frontier Deluxe, I hear ya on the negatives, but I desperately want NF in one volume.
