A vivid mid-century chrome postcard captures the jaw-dropping Gothic façade of Milan's Il Duomo rising against a brilliant blue sky, its forest of marble pinnacles and spires crowding the frame while period automobiles — mustard yellows and fire-engine reds — bustle along the piazza below, grounding this eternal monument in the lively summer of 1966. Millie, a clearly enthusiastic traveler, wrote home on July 11th of that year brimming with the day's adventures: attending Mass inside the cathedral itself, standing before Leonardo da Vinci's Last Supper, touring the Museum of Arts, wandering a "most unusual cemetery," taking in La Scala theatre, and capping it all with a shopping spree through the Galleria Vittorio Emanuele II — which she charmingly describes as "like a shopping center." The card is addressed to Conrad and his wife in Akron, Ohio, a snapshot of American tourism in postwar Europe at its most exuberant.
