1st astronauts on moon filled customs form on return to Earth

Astronauts aboard Apollo 11, which landed on the moon on July 20, 1969, filled out customs forms, a standard procedure for international travellers, on returning from their mission. Their place of departure was listed as "moon" and the astronauts declared "moon rocks" as cargo. Crew member Buzz Aldrin also shared a photograph of the signed form in a Twitter post.
