AMQS, approximately four two-stave measures marked “Allegretto,” signed “A la divine! Auber” [renowned opera composer Daniel Auber, 1782–1871]. The item has been warmly inscribed in Italian to famed soprano Adelina Patti (1843–1919) and signed by the similarly renowned singer Christine Nilsson (1843–1921); Nilsson has also penned an ode to Patti on the reverse. In fine condition, with a touch of mild soiling, otherwise fine, clean condition. A unique confluence of three opera legends! R&R COA.
