An intriguing large collection of materials from the archives of Teatro Opera Roma, the majority consisting of correspondence (letters, many of them autograph, and copies of sent telegrams) between the theater management and contracted artists, most documents dated from between 1945 and 1952, smaller part, including self-promotional material from singers applying for a contract, from the 1960s.
