Existing comment: Apollo 11 moon mail cancelled die proof, July 22, 1969:
Neil Armstrong and the Eagle crew made the first manned lunar landing on July 20, 1969. They carried this one example of official mail for the USPS, franked with this die proof of the First Man on the Moon stamp. Probably struck on July 22, the postmark is backdated to the 20th.
