On Mad Men it's the summer of 1962. I've just turned fourteen. Marilyn Monroe just died. The press wonders: Suicide or Accident? (Only later will theorists postulate that she was murdered.) The girls in the office are taking it hard. Theme of invisibility: the black elevator man who feels for Joe DiMaggio, how Betty's friend feels in her marriage. Betty is reading Katherine Anne Porter's Ship of Fools. Floyd Patterson is still heavyweight champion -- for a few more months. (Sonny Liston waits in the wings.) The song Marilyn Monroe sings over the closing credits is "I'm Through with Love," lyrics by Gus Kahn, music by Joseph A. Livingston and Matt Malneek: "For I must have you or no one, / And so I'm through with love."
