Remember that time when Carl Sagan rode a velociraptor and waved a light sabre? Here it is, commemorated in a print. (Found via several people on Twitter and Tumblr.)
The artist, Lauren Crawford, originally drew it for her boyfriend, but so many people wanted a copy of it that she put it on Etsy as print. Now you, too, can have Carl Sagan on a velociraptor on your wall.
