The Metropolitan Opera Guild Collection.

Note: This tiara was a gift from Mrs. Kathleen O’Donnell Hoover to the Metropolitan Opera Guild. Mrs. Hoover, a talented author and musician, joined the Guild in 1937 and became the Chairman of the Acquisitions and Memorabilia Committee. A key member of the organization, Mrs. Hoover was greatly involved with the Guild’s acquisitions and she herself was a generous contributor to the collection. She purchased the present tiara during the 1950s and in great charity, donated it to the Guild for all to enjoy.
