Apollo 17 lunar sample display

A goodwill gift from the Apollo 17 mission was then given by President Richard Nixon in the form of a wooden commemorative plaque display to all fifty U.S. states and U.S. territories, and 135 nations worldwide.

Eugene Cernan and Harrison Schmitt ended their walk on the Moon in 1972 with a dedication to the young people of Earth and a desire that all "live in peace and harmony in the future".

[1] They expressed hope that distribution of pieces of the rock they had collected would bring this worldwide peace and goodwill.

[1] They were presented with a letter from Nixon, stating that:[1] "... as we stretch for the stars, we know that we stand also upon the shoulders of many men of many nations here on our own planet.
