The John F. Kennedy Presidential Library and Museum takes a step back from highlighting JFK’s famed presidential years to delve deeper into his past with the new permanent exhibit Young Jack. President Kennedy’s formative years, from his childhood to young adulthood, are highlighted by items—some of which have never before been on display—that include an old school desk carved with his initials, as well as two items recently returned from an exhibit in Japan: JFK’s Navy dog tags and the coconut husk inscribed with a message that led to the rescue of him and his PT-109 crew during World War II.
