A partial set of Winston Churchill's dentures on display at Bonhams Gentleman's Library sale in London on Monday. Made just before the start of World War II and worn by the former British prime minister almost until his death in 1965, they have an estimated sale value of around 12,000 pounds ($19,000). The Gentleman's Library sale has taken place at Bonhams for the past 11 years and features a wide range of objects that may have been found in a Victorian or Edwardian gentleman's library.
