This is a very rare to find original third draft of Star Wars. The list of crew members that were issued this kind of script was very short. The movie still hadnt green light, very few people worked on the movie, with George Lucas paying everyone from his own pockets.
Its very fun to read, because all the different things on it. Did you know that lightsabers here, were not only used by Jedis? luke (before finding Obi Wan), and even the tusken raiders had one!!
Luke´s uncles do not die, Luke just leave them. And there are more than one sith lord!,
The cover is cool as it has the letter in silver, you can match this cover in J W rinzler book, The making of Star Wars.
