The shooting was delayed, allowing William Klein to explore the nooks and crannies of the city. At times accompanied by Fellini himself or Pasolini and Moravia, the young artist goes on to produce, in this enchanting context, a fresco on the city. Unlike New Yorkers, Italians do not shy away from the camera. On the contrary, they stare back at him, acknowledging the photographer's provocation.

Through Klein's lens, Rome resembles a street ballet where lovers riding on a Vespa, religious pilgrimages and the laughter of children mix with fashion scenes shot in the city's streets, such as the iconic one entitled Nina + Simone.

Roma+Klein was published in 1959 in Italie (publ. Feltrinelli) and in France (publ. du Seuil)
