[KENNEDY JOHN F.]: (1917-1963) American President 1961-63. A very small 0.5 x 0.5'' swatch of blood-stained blue leather upholstery, originally part of the rear seat of Kennedy's presidential limousine, a modified royal blue Lincoln Continental convertible with the Secret Service code name SS-100-X, removed after his assassination. Encased ('slabbed') in clear plastic with a printed CAG certification label stating, 'Assassination of JFK Blood-Stained Leather Swatch from Dallas Limo 11/22/63'. VG Kennedy's presidential limousine featured a bespoke dark and light blue leather upholstered interior manufactured by Hess & Eisenhardt of Cincinnati, Ohio. All of the privately owned upholstery sections of the limousine SS-100-X are believed to have originated from the renowned United States Presidential collection of artifacts and autographs amassed by Raleigh De Geer Amyx. It is understood that, in 1983, Amyx obtained letters of authentication from F. Vaughn Ferguson, the White House technical service representative in charge of the presidential limousine, who assisted the White House upholsterer in removing the leather from the rear seat four days after JFK's tragic assassination and supervised its refurbishing for Lyndon B. Johnson.
