Rock the Universe - modified pioneer plaque Posters and Art Prints

This is my own edited version of the public domain image engraved on plaques attached to two of the Pioneer space probes launched in the 1970's. The man in the image is usually holding his hand up waving, I've modified it so as to make the heavy rock sign. The Pioneer plaques are a pair of gold-anodized aluminium plaques which were placed on board the 1972 Pioneer 10 and 1973 Pioneer 11 spacecraft, featuring a pictorial message, in case either Pioneer 10 or 11 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.
