Installation of a New Marble Mantel in the State Dining Room

This photo of the installation of a new marble mantel in the State Dining Room was taken by Robert L. Knudsen on June 25, 1962, during the John F. Kennedy administration. The mantel was a joint gift of the architecture firm Steinmann, Cain and White, and the Marble Industry Board of New York. The new mantel was installed as part of First Lady Jacqueline Kennedy's restoration program.
