Deke Slayton’s personally-owned National Aeronautic Association lapel pin, measuring approximately 1″ long, featuring the “NAA” emblem in the center between silver wings. In fine condition. Accompanied by a certificate of authenticity from his widow, Bobbie Slayton, certifying that the lapel pin was from Slayton’s collection, though it is incorrectly attributed to Slayton’s work with North American Aviation, rather than the National Aeronautic Association.
