In the beginning of Star Wars, George Lucas had a very raw idea of where the saga would go. He hadn’t quite named it Episode IV, and when they were going to market it, they had a different name than STAR WARS altogether. Below is a video clip of how the design of the name and the logo went through many incarnations and it’s pretty cool to look at.
