The New Adventures of Superman (1966)

An animated series about the hero made famous in comic books and later in a live-action TV show. Superman, visitor from the planet Krypton and alter-ego of mild-mannered reporter Clark Kent, has made it his mission to stop crime on his adopted home of Earth. His crime-fighting frequently pitted him against the master villain Lex Luthor, but somehow the caped crusader always managed to thwart Luthor's plans.
