I'm pretty sure that is the be all and end all of Archie's smattering superhero-gags on the cover of Josie. "He's the only superhero who can kiss in A/C or D/C current" is a most peculiar gag. The other cover can be recylced with any glut of superhero titles in any era of comic book history.

I note that the "by Dick and Dan" label disappeared from the title with issue #41 (or maybe #42, I'd have to check), which has a story that sort of preludes into Josie and the Pussycats... meaning it ceases to be "Dick and Dan"'s creation (though better to say "Frank Doyle and Dan Decarlo", who are after all the creators of the comic book) and is now the domain of the company.
