The story behind the rocking chair, and how it came to symbolize Camelot, is well known. Suffering from chronic back pain as a result of injuries he sustained while in the Navy, Kennedy could not remain seated in the same position for long periods. The White House physician prescribed the use of rocking chairs, and one was placed anywhere the president routinely sat. The Oval Office rocker became famous from the countless press photos of Kennedy sitting in it, and was the inspiration for this lapel pin, issued in late 1963, just prior to Kennedy's assassination.
