Found this comic book scanned on Golden Age Comic Book Stories (I highly recommend the site).
Makes for an interesting early version of the "Gamma World". Here, we have an alien invasion instead of nuclear war - even better, an alien invasion after everybody disarmed. The volta men are ragged looking aliens sporting pickelhauben, talking like Yoda and fretting over another group of aliens from Venus - the sponge people (no, not this guy). If I'm being completely honest, I think I prefer this to nuclear apocalypse-land.
