Luke wasn't always a Skywalker; the original title of A New Hope was The Adventures of Luke Starkiller as taken from the 'Journal of the Whills'. A signed early edition of that script is part of a super cool selection of Star Wars memorabilia up for auction, including storyboard sketches and concept art.
The films are so familiar now that it's difficult to imagine a time when Landspeeders and AT-ATs only existed as hand-drawn illustrations, ultimately made into movie magic by Industrial Light and Magic; now these artifacts represent a turning point for the visual effects industry, which evolved at lightspeed leading up to and through pre-production and filming of the epic trilogy.
On October 17th, Profiles in History is putting these items up on the block for deep-pocketed sci-fi fans ready to drop anywhere from $US600 to $US15,000 for a piece of cinematic lore. It's part of the massive Hollywood Auction 65 [PDF] — for the curious, there's lots of other treasures to be found too. (The boxing gloves Sylvester Stallone wore to bout with Mr T. in Rocky III? They can be yours.)
