'Your papers, please' must never be heard in America

Each year, many tourists journey to the Convent of Santa Maria delle Grazie in Milan, Italy, to see Leonardo da Vinci's "The Last Supper." This awe-inspiring mural, crafted between 1495 and 1498, depicts the reactions of the 12 apostles after being told by Jesus that one of them would ultimately betray him.
Mr. King writes that "The Last Supper" "is arguably the most famous painting in the world," aside from the "Mona Lisa," but its "tremendous fame is detached from what we see before us in the refectory."
