Ouroboros, an image of a snake devouring its tail, is an ancient symbol of eternity, rebirth, renewal, and infinity. Surrounded by and coiled around two awesome photographs courtesy of the Hubble Space Telescope and NASA, it is a reminder of the eternal wonder and beauty of the cosmos. While the base image is 'locked', all text is a template object and can easily be changed or deleted. This design is also available on many other products here at Bon Ton Designs. We have mugs.
