This is from Filmation's 1966 Saturday morning cartoon, “The New Adventures of Superman,” which is probably my first encounter with the Man of Steel. In an episode entitled, “The Mermen of Emor” (written by Oscar Bensol), Clark and Jimmy are in Italy, for some reason, and they come upon a mystery: experienced scuba divers going missing off the coast. Turns out the title characters are responsible. The mermen capture the divers, bring them to some underground lair, and use them in gladiatorial-like contests. (That's why Italy.) At this point in the story, Jimmy's gone missing, while Clark, oblivious, is simply enjoying a nice espresso at an outdoor cafe. Love the expression on his face. “What, a man can't wear an ascot, and drink espresso in outdoor cafes in Italy, without people talking?” Nope, apparently not.
