ブルージェット 付録 [Blue Jet Furoku / Blue Jet Supplement]

A short-lived 1960s Shueisha supplement, Blue Jet Furoku ran for just three issues, with artist 堀江卓 providing the most frequent visuals. This obscure series represents an early, experimental moment in Japanese publishing, offering a glimpse into the formative years of the manga industry. Though brief, it's a footnote for collectors and historians exploring Shueisha's mid-century output.
