Up for sale is a limited edition (No. 077908) souvenir cover of "A Tribute To Space Exploration" joint issued by USPS and NASA in 1994.  The attached certificate proved that the $9.95 Moon Landing stamp  (1 of the 500,000 stamps) was flown on the shuttle Endeavour, during its Fall 1994 flight into space.  It is a good chance to own a piece of stamp which was travelling in space. 

Shipping & Handling is $0.50 on each additional item. Happy Bidding!
