| An Apollo 1 cover from "Space City Cover Society", featuring a navy "SPACE EXPLORATION NASA" printed cachet, postmarked at Houston, Texas with a rare machine cancel on January 27, 1967. Houston postmarks from this date are scarce, making any Apollo 1 cover serviced there particularly desirable. Houston was also home to the Mission Control Center for the Apollo 1 tests. Only 100 covers from the “Space City Cover Society” were serviced in Houston, Texas, on that day. |

| An Apollo 1 cover featuring the "KSC Officials" stamped cachet, postmarked at Kennedy Space Center with a very rare machine cancel on January 27, 1967. As the KSC post office closed at 6:30 p.m., these covers were backdated. Only 40 covers bearing the “AS-204” cachet were produced, making this an exceptionally scarce cover. |

Also postmarked at Kennedy Space Center with a hand cancel on January 27, 1967, probably because the original machine cancel did not strike the affixed postage stamp. |
