Another Kirby. No story in the world is going to live up to the potentials imagined by this cover image.
It’s also an early example of Stan Lee’s hyperbolic cover copy, albeit in a restrained way. It’s a bit dicey to refer to your own work as a ready-made classic, after all–though Stan could usually pull this sort of thing off by being simultaneously self-effacing and also clearly having his tongue in his cheek.
Good pop on the monster, good, novel composition–but it’s really the bright red balloon with the white and yellow copy that puts this one over the top.
