According to Scott, the astronauts also decided the covers would make good gifts and requested an additional 100 each for a total of 400 covers. Scott indicated in his testimony that after discussion with his crewmates, he expected the covers to be a "very private and noncommercial enterprise." He added: "I admit that this is wrong. I understand it very clearly now. But at the time, for some naive and thoughtless reason, I did not understand the significance of it." Irwin wrote in his autobiography that the initial meeting with Eiermann took place in May 1971, and that the astronauts met with him twice thereafter. Eiermann relayed instructions from Sieger on how to prepare the covers: they were to be postmarked twice, at KSC on the date of launch and on the recovery ship on the date of splashdown, and carry a signed statement from the astronauts with a certification from a notary. The certification would make the covers more sellable in Europe, where a notary is a legal professional who often verifies the document, not just the signatures.
