TALES OF SUSPENSE #39 (March 1963)
Art by Don Heck and Stan Goldberg
Words by Stan Lee & Larry Lieber
I've always thought it'd be wild if humanity ever entered an irl sci fi future scenario and met another alien race, let's call them the Quacksians, because like, all previous sci fi would be invalidated and all future sci fi would have to include the Quacksians because that's the new baseline reality(and would Quacksians show up in future fantasy fiction alongside humans?). Then I realized that's what happened to a lot of stories when the moon turned out barren. Funny how these things happen.
