Fun fact: in 1963, the year in which Season 3 occurs and in which Don and Betty Draper visit the Rome Hilton, The New Yorker ran a story by Harold Brodkey (a writer dear to Emily’s heart) set in Rome!
It ran in the issue dated November 23, 1963, so the people who read it right after the issue hit the newsstand/mailbox (say, November 18?) were thinking about something completely different a few days later. Because of events that will surely be covered in Mad Men before this season is out.
