This is a complementary piece for your C76 FDC Collection. This is not a first day cover. A Fleetwood Cachet for C76 was modified with a label pasted over the Fleetwood name that states: Commemorating Man's first flight at Kitty Hawk and Man's first visit to the Moon. Inside is a Christmas letter from Burroughs, Wellcome & Co dated December 17, 1969. The letter explains that the cover brings together the incredible achievements of man's first flight and the first ...landing on the Moon. The cover is cancelled on December 17, 1969, the 66th anniversary of the Wright Brothers first flight at Kitty Hawk, NC. And, about three months after the Moon Landing stamp was issued. Very clean cover. No postal markings on reverse and backflap is unsealed. Low starting price and FREE SHIPPING to US locations...I mail at least twice a week. For International customers S&H will be $2.50 flat rate for each cover. I will discount S&H costs for multiple covers purchased over a one week period. Please ask me for an invoice before you pay.
