The three astronauts and an acquaintance, Horst Eiermann, had agreed to have the covers made and taken into space. Each astronaut was to receive about $7,000 (). Scott arranged to have the covers postmarked on the morning of the Apollo 15 launch on July 26, 1971. They were packaged for space and brought to him as he prepared for liftoff; he brought them aboard in a pocket of his space suit. They were not included on the list of the personal items he was taking into space. The covers spent July 30 to August 2 on the Moon inside "Falcon". On August 7, the date of splashdown, the covers were postmarked again on the recovery carrier . One hundred were sent to Eiermann (and passed on to Sieger); the remaining covers were divided among the astronauts.
