The Apollo 17 lunar sample display consists of a Moon rock fragment from a lava Moon stone identified as lunar basalt 70017, the recipient's flag and two small metal plates attached with descriptive messages. A goodwill gift from the Apollo 17 mission was then given in the form of a wooden commemorative plaque display individually to all fifty states, five U.S. territories, and 135 nations worldwide.
Eugene Cernan ended his walk on the Moon in 1972 with a dedication to the young people of Earth. The theme of his speech from the Moon was the wish for peace and harmony among the people of the world. He explained that, Harrison Schmitt, his fellow astronaut on the Moon with him had just picked up a very significant Moon rock that they hoped would bring this worldwide peace through the distribution of its fragments. This basalt was later identified as lunar basalt 70017, dubbed the "goodwill rock".
Once brought back, this Moon rock was broken up into small fragments and distributed in 1973 by President Richard Nixon to all the countries of the world and to the United States with its territories as a goodwill gesture.
The "goodwill moon rock" fragment of 1.14 grams was placed inside a solid piece of acrylic lucite, the Moon rock being embedded inside the Lucite material when it was molten. The clear plastic ball was about the size of a billiard ball and partially flat at the bottom. It was then mounted and glued onto a 10 inch by 14 inch wooden plaque.
The next item directly below the Lucite ball was attached a metal plate of about 2 inches by 4 inches that read:
The fragment is a portion of a rock from the Taurus Valley of the Moon. It was part of a larger rock composed of many particles of different shapes and sizes, a symbol of the unity of human endeavor and mankind's hope for a future of peace and harmony.
The recipient's flag of about 4 inches by 6 inches (precisely 10.16 cm x 15.24 cm) was mounted directly below this metal plate covered with a clear plastic cover.
Another metal descriptive plate was attached directly below the recipient's flag that read:
This flag of your state was carried to the moon aboard Spacecraft America during the Apollo XVII mission,
