500.000 positives from the first half of the 1900s. The archive was begun in the early 1900s, initiated by Corrado Ricci, then Director General (1903–1909). It consists of photographs from various sources, equipped with the practices of office, material for scientific publications and copies received by the Directorship General on the basis of the R.D. 29-3-1923, n. 798 which decreed the obligation, on the part of public or private bodies, to send to the Director two copies of every photograph reproduced of “ movable and immovable things of historic, archaeological, paleo-ethnological, and artistic interest”.
