The study in the Puccini home, with decoration of the walls, in tempera, with patterned ribbons and garlands on a blue background (about 1910), housed the rich family library, with the scores of all the compositions of the Puccinis, music by other composers and valuable and important musical treatises.

Today it houses the costume for Act II of Turandot, donated by Maria Jeritza, in memory of the first production of the opera at the Metropolitan Opera House in New York (1926).
