Justice League of America #57

Published by DC Comics in September 1967, Justice League of America #57 represents a notable period for the Silver Age title. The issue was written by Gardner Fox, a prolific architect of the DC Universe who helped define the team's early dynamics, and featured cover art by Carmine Infantino with interior illustrations by Mike Sekowsky. During this era, the Justice League served as the flagship team book for DC, frequently bringing together its most recognizable icons to tackle cosmic threats, reflecting the expansive and adventurous tone of 1960s superhero storytelling.

The narrative follows the team as they encounter the mysterious Hourman, a character whose inclusion highlights the series' dedication to integrating various legacy heroes into the core JLA lineup. Critically, the issue is remembered for its role in maintaining the continuity and collaborative spirit of the Silver Age DC universe, which sought to balance character-driven drama with high-stakes action. While not as frequently cited as the team's first appearance, it remains a characteristic example of the collaborative craft between Fox and Sekowsky, whose work together solidified the JLA as a cornerstone of the medium.
