Two large swatches of light and dark blue seat leather from the 1961 Lincoln Continental X-100 presidential limousine Kennedy was riding in at the time of his assassination. The swatches are taped together to an overall size of 7″ x 3″, with the tape on the underside of the leather accordingly marked in blue ink, “Center” and “Border.” In overall fine condition. Includes a detailed letter of provenance on White House letterhead from F. Vaughn Ferguson, a technical service representative at the White House whose primary responsibility was the care of the presidential limousine. Important to note that only Mr. Ferguson was permitted continual hands-on contact with the 1963 presidential limousine after the tragic assassination of our president. In part: "Four days after the Assassination the White House upholsterer and I removed this leather at the White House. The light blue leather is from the center of the rear seat. The dark blue leather is from the border of the rear seat. The spots on the leather are the dried blood of our beloved President, John F. Kennedy." Ferguson was able to retain the removed leather sections, and then the presidential limousine was sent to a Cincinnati firm for refitting and a security upgrade. A desirable set of both types of leather upholstery in the 1961 Lincoln Continental X-100 presidential limousine and a poignant, historic reminder of that fateful November day.
