Justice League of America #47

Justice League of America number 47 was published by DC Comics in September 1966. It arrived during the height of the Silver Age of comics, a period defined by the revitalization of superhero properties through imaginative, high-concept storytelling. This issue was part of the ongoing title created by writer Gardner Fox and artist Mike Sekowsky, who established the team's signature format of gathering diverse iconic heroes to face cosmic or multifaceted threats that individual characters could not overcome alone.

The issue features artwork by Mike Sekowsky and Bernard Sachs, with a cover by Carmine Infantino. The creative team aimed to maintain the title's momentum by leaning into the imaginative world-building and dynamic team interplay that had made the Justice League a cornerstone of the DC universe. As with most issues of the era, it served both as a standalone adventure and as a continuation of the intricate lore being built around the Satellite era's precursors, receiving consistent readership from a demographic eager for serialized, large-scale superhero conflict.
