Action Comics #240

In "Secret of the Superman Sphinx," Lois Lane stumbles upon a Clark Kent robot hidden in a Daily Planet closet, while a mysterious Sphinx—its face a striking likeness of Superman, eyes glowing with kryptonite vision—suddenly ascends into orbit above Earth. The story unfolds as the two enigmas intertwine, setting off a chain of events that tests the limits of identity, trust, and the very nature of heroism.

In "Trapped in the Insect World," Bill and Janu join Professor Wakely on a perilous quest through towering grass, searching for a missing component to power his shrinking ray—only to find themselves shrunk to an inch tall, where ordinary insects loom as colossal threats. The story unfolds with tense, grounded urgency as the trio navigates a world turned alien and dangerous, each blade of grass a forest, each drop of dew a lake.
