The original Luke Skywalker was released in 1978, although it was produced in 1977. This figure was available to send away for in the early bird packages. The Luke did have a major variation diffrence. First off, the light saber was produced standard (could be pulled out once) and also double-telescoping (could be pulled out twice). The double telescoping is worth alot more money then the standard more common Luke and is highly sought out for by collecters. It was mainly produced in the early bird special package and it is rare seen in 12 backs (the first 12 star wars figures produced). The Luke also can be found with blond and brown hair. 2 variations of redish hair have been found also. Check out http://www.rebelscum.com/VINtLuke.asp for more detailed information.
