Carl Sagan & Frank Drake's Pioneer plaque. It was created in the event that either the Pioneer 10 or Pioneer 11 spacecrafts are detected and recovered in the remote future by advanced extraterrestrials.

The Pioneer plaques, a pair of gold-anodized aluminum plaques which were placed on board the 1972 Pioneer 10 and 1973 Pioneer 11 spacecraft, featuring a pictorial message, in case either is intercepted by extraterrestrial life. The plaques show the nude figures of a human male and female along with several symbols that are designed to provide information about the origin of the spacecraft.
