Charles M. Duke, Jr.” Cover bears two cancellations, one from the Kennedy Space Center on launch day April 16, 1972 and the other from the day of recovery, April 27, 1972 on the recovery ship USS Ticonderoga. In fine condition, with some mild toning on reverse. Accompanied by a certificate of authenticity from Duke stating “The covers accompanied me during the flight and to the Descartes lunar landing site,” as well as two photos taken at time of signing.
