The first three Space Museum stories were reprinted in the DC Comics science fiction reprint anthology, From Beyond the Unknown #23 -25 (July/August 1973 - November/December 1973), but the title was then cancelled. Eighteen years later writer Gerry Conway re-introduced the Space Museum concept in "The Secret that Time Forgot" in Justice League of America #206 (September 1982), and in 1984 writer Paul Kupperberg followed in The New Adventures of Superboy #50 (February 1984), this in a 30th-century Legion of Superheroes framing sequence by Keith Giffen around a modern-day Superboy story by Kurt Schaffenberger.
