Type: Transformation1950s comics often seemed like it was all about giant props, or perhaps, making the heroes tiny as they raced across giant typewriters. In "The Shrinking of Superboy", everything becomes a giant prop as the Boy of Steel starts to shrink!
It all begins when Professor Lang finds the space capsule from Doctor Who's "Fear Her". Behold:
Clark's microscopic vision sees little aliens inside, and these shoot a harmless beam at him. Later that day, Superboy realizes he's shorter than a life-size statue of himself! (Because 1950s, that's why.) Soon, he's the size of a midget, of a cat, and then of a toy. You know what else seems to have shrunk?
The Shakespearean canon. Damn you Roland Emerich! Anyway... Superboy is caught by Lana and has to make like he's a wind-up doll, and then fly home to give Clark Kent some cover. Lana can't see him because he's busy doing homework. Proof: You can hear the typewriter going up in his room. The real reason for this sequence is of course that all these stories MUST, by law, feature a giant typewriter.
Then there's a ridiculous sequence where Superboy hides from Lana in the middle of a dart board, and she decides to play a game and he has to deflect the darts with super-breath so that they don't shatter on his tiny body. Then he helps his Ma do some sewing. Then he stops a bullet from the gun of one of those Smallville hitmen. Punches a giant mosquito. And FINALLY, he's small enough to enter the alien spaceship. Twist: They don't want to fight him, they want his help. Seems like a meteor caused them to crash and they need super-powered repairs to get the rock out of their hull. This done, they fly off.
And Superboy keep the meteor as his smallest trophy yet, the size of a grain of sand. (Superman Museum officials in the 30th century tell me they hate this exhibit, which is both unpopular and hard to keep track of.)
