The Avengers #100

The Avengers #100, released by Marvel Comics in June 1972, served as a significant milestone for the series, marking a century of publication for Earth's Mightiest Heroes. Written by Roy Thomas with cover art by Barry Windsor-Smith and interior pencils by Barry Windsor-Smith, the issue focused on the 'Kree-Skrull War' aftermath and featured a massive gathering of nearly every character who had served on the Avengers roster up to that point. The narrative was designed as a celebratory climax that emphasized the team's expansive history and the interconnected nature of the Marvel Universe.

The creative intent behind this issue was to capitalize on the momentum of the ambitious Kree-Skrull arc, utilizing a sprawling assembly of heroes to reward long-time readers. Barry Windsor-Smith's contribution is noted for his distinct, flowing illustrative style, which contrasted with the house style often seen in Marvel titles of the era. The issue was received as a landmark event in Silver Age comic history, effectively cementing the title's status as a flagship series and establishing a tradition of using centennial issues to highlight the legacy of team-based comic storytelling.
