Neato Coolville has put together this animated GIF of Ralph McQuarrie's original cover art to the novelization of Star Wars which appeared in December 1976 under the name of George Lucas (although the true author was Alan Dean Foster). I hadn't seen this original cover before.
(If you want to see a non-animated version, click here.)
