The museum received from an Italian private collection 47 letters from Arturo Toscanini, Enrico Caruso, and Giacomo Puccini to Krushelnytska — a unique epistolary archive from 1898-1924.
In November 2025 the Solomiya Krushelnytska Memorial Museum received in its collection forty-seven personal letters from three central figures of the Italian operatic school of the late 19th — early 20th centuries, addressed to the Ukrainian singer. The transfer was made from the private collection of the Brembilla family (Milan) through inter-museum partnership with Teatro alla Scala. The set includes: 18 letters from Arturo Toscanini (1867-1957) of the 1898-1925 period, including discussions of Aida, Tosca, Wagnerian cycle productions; 15 letters from Enrico Caruso (1873-1921) of the 1903-1920 period, where the legendary tenor discusses Krushelnytska's scenes at the Metropolitan Opera; 14 letters from Giacomo Puccini (1858-1924), including the key letter of 14 June 1904 with gratitude to Solomiya for saving Madama Butterfly.
The central exhibit of the archive — Puccini's letter of 14 June 1904, in which the composer writes: 'Solomiya, you saved my Cio-Cio-San from silence. Without your voice in Brescia on 28 May this work would have been dead. I am your eternal debtor'. This quote will enter the permanent museum exposition. Letter restoration will continue until spring 2026; the first scientific presentation with the full catalogue — in March 2026.
