I'd be willing to wager 50,000 quatloos that Jim Lee, Geoff Johns and Dan DiDio have this comic in their collections:
That scene on the cover really happens--Wonder Woman rescues Lois from a runaway race car--and Superman decides this is the appropriate time to drop the hammer:
They even go so far as to title the story:
Well, the propensity of DC superheroes of the era, Lois suspects that it's just some silly ploy. Yet, after stalking the hell out of the couple for awhile, Lois comes to the sad conclusion:
What's that, you say? The story's not over yet?
Or, perhaps Silver Age creators were too primitive to understand that OF COURSE you have to break-up long-standing relationships in order to pair your most powerful characters romantically...people should always be matched up by superficial similarities!! Yeah, that's the ticket!!
Which is why I wish DC had control of Tarzan right now--because of course he shouldn't be married to plain old Jane--he should be with another jungle charcter, like Sheena or Rima or Pantha or...
And Beauty And The Beast? Give me a break. A Beast should never be matched with a non-beast...what kind of relationship is that?
Lois Lane #136 is from 1974
