Extremely rare sterling silver serving fork made by Tiffany & Company for the family of 'Commodore ' Cornelius Vanderbilt ( 1794-1877), who earned his title as head of a steamship line which plied the waters around New York City and eventually as far away as San Francisco and France. The Commodore and his first wife, Sophia Johnson Vanderbilt, had thirteen children, including William Henry (1821-1885), and Tiffany created private patterns for the families of William Henry's famous sons, Cornelius (1843-1899) and William Kissam (1849-1920. Both designs were by Charles Grosjean and were very ornate. This William K.Vanderbilt pattern features a family coat of arms in relief on the front of the terminal. The reverse of the handle has a WVK monogram along with symbols of the chase ( a stag's head,horn,quiver) and a dependent tassel. The stem reverse is covered by' bunches of laurel leaves,extending to a grotesque mask on the heel. The server measures 7 3/4" long and is marked Tiffany & Co.,Sterling.
