A very interesting collection of opera arias by Gounod, Bizet, Massenet, Charpentier, and Puccini, owned and used by the important soprano of the Opéra-Comique, Paris. 7 pieces of sheet music are signed by Brothier on their covers and contain many performance markings such as dynamics, tempo markings, cuts, breathing and phrasing marks, in bold pencil and colored pencil. Also included is a copy of Satie's song Le Chapelier, not signed by Brothier but with the typewritten name of a M. Th. Ducuing at the upper right.

The music shows signs of heavy use, with much of the music reinforced with tape or fabric tape, the Puccini copy with loose pages, and general overall toning and edge wear. Overall in very good condition and a very interesting record of the great soprano's repertoire.
