The new production debuted on December 12, 1940, with Jussi Björling as Manrico, Norina Greco as Leonora, and Frank Valentino as the Count Di Luna with Ferrucio Calusio conducting. The production remained in the Met's repertory through 1956. She also designed the costumes for Lee Simonson's production of Richard Wagner's Ring Cycle for the Metropolitan Opera in 1948.[4]
