Apollo 11 goodwill messages

At the top of the disc is the inscription: "Goodwill messages from around the world brought to the Moon by the astronauts of Apollo 11."

NASA head Thomas O. Paine proposed the idea to the U.S. State Department, and corresponded with world leaders to solicit their messages.

These were enshrined by being photographed and reduced to 1/200 scale ultra microfiche silicon etching.

The disc was in a package in Buzz Aldrin's suit shoulder pocket along with some other memorial items.

He was reminded about the package by Neil Armstrong while ascending the ladder of the Lunar Module Eagle to finish their EVA.
