The X-Men #6

The X-Men #6 was published by Marvel Comics in July 1964, arriving during the burgeoning Silver Age of comic books. At this stage, the series was struggling to find a consistent audience, and the creative team of Stan Lee and artist Jack Kirby were tasked with expanding the team's rogues' gallery. This issue is notable for being the first appearance of Namor the Sub-Mariner in the X-Men title, a character who had been a staple of Timely Comics, Marvel's predecessor, since 1939.

The narrative design reflects the period's standard approach of pitting heroes against established icons to generate interest. Jack Kirby’s energetic, muscular illustration style served to define the visual language of the Marvel Universe during this era. While the issue did not initially ignite the massive sales figures that later iterations of the franchise would see, it remains a significant touchstone for collectors as it bridged the gap between the golden age of superheroes and the modern X-Men mythos.
