On This Day, 1970
Yoko Tsuno Makes Her Debut in Spirou

On September 24, 1970, Belgian cartoonist Roger Leloup introduced the world to Yoko Tsuno, an electronics engineer turned interstellar adventurer, in an 8-page short story titled "Hold-up en hi-fi" published in the Franco-Belgian magazine Spirou. It was a quietly radical moment for the medium: a Japanese woman anchoring a long-running European science-fiction adventure series, decades before "representation" was even part of the industry's vocabulary. Two more short pieces followed before Yoko's first full-length adventure, "Le trio de l'étrange," began serialization in Spirou on May 13, 1971. The series is still running more than 30 albums later, and Leloup — a former animator who worked on Hergé's Tintin studio productions — is remembered as one of the great craftsmen of European bande dessinée science fiction.

Jack Kirby's Final Fantastic Four Issue Hits Stands

Fantastic Four #102 (cover-dated September 1970), pitting the team against Namor and Magneto, marked the last issue Jack Kirby illustrated during his original run on the title he co-created with Stan Lee. After a decade that produced the Galactus Trilogy, the Inhumans, and the Black Panther, "The King" was headed for rival DC Comics, where he would launch his Fourth World saga. Marvel later used unpublished Kirby pages to patch together issue #108, but #102 is the one historians point to as his true send-off from Marvel's First Family.

DC1970
DC marked a milestone issue with The Flash #200, written by Robert Kanigher with art by Irv Novick and Murphy Anderson. It was one of several DC and Marvel books hitting newsstands the same week — a reminder that round-number anniversary issues have been a comics tradition for well over half a century.
Silver Surfer #18 Closes Out the Original Series

The same week, Marvel's original Silver Surfer series came to an end with issue #18 — a title Stan Lee had envisioned as his most personal, philosophical superhero book. Low sales cut the Surfer's solo adventures short after only 18 issues (plus one giant-size annual), though the character would go on to headline multiple revivals in the decades that followed. DC's tryout anthology Showcase also wrapped its own run around this same period with issue #93, closing out the title that had launched the Silver Age of Comics back in 1956.

Crumb, Harvey Pekar, and Denis Kitchen's own Mondo Snarfo and Bijou Funnies contributors.

Panel of the Day — Trivia
Yoko Tsuno wasn't just a female lead in a genre dominated by men — she was an engineer, routinely out-thinking alien civilizations with physics and electronics rather than punches. Roger Leloup, who'd spent years drawing sleek machinery as a background artist on Hergé's Tintin studio team, gave her some of the most meticulously rendered spacecraft and technology in 1970s European comics.
