NASA did up some posters celebrating the 40th anniversary of the Voyager spacecraft (Voyager 1 launched September 5, 1977). I’m digging this K-Tel themed one. There is actually a gold record containing images, music, mounted to Voyager (one side of it is shown on the bottom of the poster) in case someone from another civilization finds the spacecraft - or crashes into it with their flying saucer. The golden record’s contents were selected for NASA by a committee run by Carl Sagan. You can check out the contents at JPL’s site or at Wikipedia.

Here’s the other posters in the series (all are available as super high res PDFs or TIFs for poster size reproduction):
