Among the many things gripping the imaginations of children in the late 1950s were the emerging superheroes of the Silver Age of comics (1956–1969) and the beginnings of the space race. DC Comics decided to combine those two interests by launching a pair of space heroes in its tryout comic book Showcase. The first to appear was the futuristic spaceman, Space Ranger, while the second (who premiered in Showcase #17 in late 1958) was Adam Strange, overseen by longtime science fiction fan and editor Julius Schwartz. His first choice as artist was Carmine Infantino, but, as Infantino was currently entertaining the troops in Korea, Mike Sekowsky was drafted in for the three Showcase issues. When these proved popular, Strange moved over to the Mystery in Space comic, where he enjoyed a run of fifty issues, most of them drawn by Infantino and written by the prolific Gardner Fox.
