Bates, Swan and Roussos attempt to re-capture the joyous insanity of the early 60s Superman stories in Action 388 (May 1970).
The story, such as it is, has Superman come back to Earth after a mission in space, and find that everything has turned crazy. Sgt. Rock is his romantic rival for Lois Lane. Every panel holds bizarre details, which are occasionally humourous. There are also a few cameos – note Enemy Ace flying by in the last panel above.
Lex Luthor, Brainiac, Mr. Mxyzptlk and Bizarro all appear in the tale, though none are the villain of the story.
The Legion make a cameo, in probably the most serious couple of panels, as Cosmic Boy, Lightning Lad and Saturn Girl warn Superman that Lois Lane is an idiot.
There is an explanation, of sorts. Superman has wound up on a weird mirror-world, thanks to a bumbling scientist. They both return to the real Earth at story’s end.
It’s not a bad story. It’s not as funny as they would have liked. If anything, it shows what an achievement the early 60s Superman stories were.
