ファイト兄弟 付録 [Fight Brother Furoku / Fight Brother Supplement]

A single 1965 supplement from Shueisha, Fight Brother Furoku is a one-shot comic by artist 貝塚ひろし. Its brief existence marks a small, self-contained moment in the publisher’s mid-60s lineup, offering a glimpse of the era's energetic, stand-alone storytelling.
