A pilot was produced in 1969, but anime adaptations of Monkey Punch's famous, not-so gentlemanly gentleman thief began in earnest in October, 1971 with the first of three Lupin III TV series. Gearing up for the December special Lupin the III: Chi no Kokuin ~ Eien no Mermaid, a new trailer with design by Redline's Takeshi Koike promotes the anime's 40th anniversary.
