FINE AND RARE APOLLO 16 CREW-SIGNED INSURANCE COVER, canceled on the day of launch, April 16, 1972, at the Kennedy Space Center, FL., official cacheted cover, clear, bold signatures from all three crew members John Young, Ken Mattingly, and Charlie Duke. Reserve. 3 5/8" x 6 1/2".
Catalogue Note: Insurance covers were a tradition that started with Apollo 11 and continued through Apollo 16. The astronauts from each mission would sign a batch of these covers to be left on Earth as a contingency against their failing to return safely from the moon. In the case of a tragedy, the covers would be sold with the proceeds benefiting their families, similar to an insurance policy.
 

From a private Connecticut estate collection.

Excellent condition.
