This post is exactly what the title says. All the early Actions without Superman on the cover. The later ones have him in the inset, but don't feature him. These are both awesome and kind of weird, because Superman turned out to be such a big deal and they didn't initially realize what kind of a phenomenon they had on their hands.
Enjoy!
