Apollo 17 lunar sample display

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 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.
