Apollo 11 'Type 3' insurance cover with a cachet of the mission insignia, bearing a July 16, 1969, Kennedy Space Center cancellation, numbered on the reverse “BA01,” signed in blue felt tip by Neil Armstrong, Buzz Aldrin, and Michael Collins. The cover is lightly affixed by three corners to a signed letter of authenticity from Buzz Aldrin on his own personal stationery which reads, in part: “This postal cover with the Apollo 11 emblem cachet is one of the ‘insurance covers’ signed by the Apollo 11 crew before our launch on July 16, 1969…The cover displayed above has been in my private collection since 1969 and has an identifier of BA01 written on the reverse side. It was signed by the Apollo 11 crew—Neil Armstrong, Michael Collins, and myself prior to launch.” In fine, bright condition. The ‘Type 3’ cover rates as the least commonly found of the three Apollo 11 insurance covers and is highly sought after by collectors; this one is further enhanced by its impeccable provenance from the second man on moon.
