Mysteries of Unexplored Worlds #16

In "The Giant Bubble Threat," a man and his nephew find themselves whisked from a routine flight to the Moon, where they encounter its surprisingly welcoming inhabitants. Back on Earth, they discover their adventure left no trace—time remained untouched, thanks to a mysterious "reverse time bolt," making it seem as though they never left at all. Cover by Dick Giordano, this 1960 Charlton issue delivers a quietly surreal sci-fi journey with a twist that lingers long after the final page.
