Everyone remembers the dark-blue Lincoln Continental limousine in which John F. Kennedy was shot in Dallas on November 22, 1963. It is arguably the most well-known car in history. But here’s a question for experts on J.F.K.’s assassination: What was the last automobile from which the president stepped out alive that day?

It was, in fact, a white, open-topped Lincoln that Kennedy, the First Lady, and Texas governor John Connally rode in that morning. They rode in a motorcade from a breakfast speech at the Hotel Texas through Fort Worth, and then on to Carswell Air Force Base to make the short, fateful flight on Air Force One to Dallas.
