Extraordinary and exceedingly scarce souvenir typescript, a lengthy excerpt from the exchange between the moon and mission control during the Apollo XI mission, including Armstrong’s famous quotation, “That’s one small step for a man, one giant leap for mankind,” one page on onionskin, 8.5 x 11, signed by all three astronauts from the mission. Armstrong has signed in blue felt tip, “Neil Armstrong, 1-5-77”; Collins has signed in ballpoint, “Michael Collins, Apollo XI CMP”; and Aldrin has signed in ballpoint, “Buzz Aldrin, Apollo XI LMP.” Accompanied by two certificates of authenticity from Novaspace Galleries certifying Collins’ and Aldrin’s signatures and including photos taken at the time of signing, and a letter from John Reznikoff of University Archives certifying, through provenance and forensic analysis, that the signatures were obtained after the document was typed (i.e., with the signers’ full knowledge of the contents). In fine condition, with faint horizontal fold, well away from signatures, and subtle blurriness to Armstrong’s signature due to the nature of the felt tip on onionskin. COA Scott Cornish and R&R COA.
