The Apollo 11 lunar sample display is a commemorative podium style plaque display consisting of four dust particle specimens (dubbed "Moon rocks"), the recipient's flag and two small metal plates attached with descriptive messages. The Apollo 11 plaques were given as gifts in 1970 by President Richard Nixon to 135 countries, the 50 states of the United States and its territories, and the United Nations.
With the exception of Venezuela, whose actual flag was not flown to the Moon on Apollo 11, the wording on the plaque (with the appropriate name filled in) was:
The New York Times reported in 2012 that gifts of moon rocks were not well tracked or managed by NASA.[1] Within the US, public gifts require legislation to be transferred, but other nations set their own laws.

Robert Pearlman of collectSPACE has also tracked the displays.[2]
