The Carabinieri in Turin recovered five handwritten sheets of paper by Benito Mussolini, which contained notes from his meeting with Adolf Hitler on April 22, 1944, at Klessheim Castle in Salzburg, and returned them to the Ministry of Culture. The investigations were prompted by inspections of the antiques market in response to an allegation of holographic letters available for sale at a well-known Turin auction house. Initial investigations indicated that the handwritten sheets, offered for sale by a private individual through the auction house, had annotations in Mussolini's handwriting, as well as the author's own monogram "M" at the bottom of the last sheet. The remarks include subjects of significant historical interest. They contain a detailed list of various subjects, neatly divided into three broad themes: "Armed Forces", "Politics", and "Economy and Labor". The papers are undated, but their content largely corresponds to the topics discussed by Mussolini and his close circle of collaborators during the meeting with Adolf Hitler. Consequently, the papers can be almost undoubtedly identified as the notes that Mussolini prepared for the meeting, and they are likely the same ones that were used during the conference in Germany. It has also been confirmed that the documents had been in the antiques market for some time, most likely since Mussolini's personal archive and the archives of several organs of the RSI (Italian Social Republic) vanished in the chaotic aftermath of the war in April 1945.
