I'm an unabashed Star Wars geek. The legendary story George Lucas created has been an inspiring influence on me & every generation since its release, around the time I was born.
The original movies owe much of their design & visual appeal to the creative abilities of artist Ralph McQuarrie.
This visionary recently passed away, but the saga he helped develop will continue to inspire people of all ages for quite some time.
Not only did he create the look of the Star Wars universe, but he also helped with the production of many other hit movies, like Raiders of the Lost Ark, E.T., and Jurassic Park.
Here are some galleries of Ralph McQuarrie's art for the Star Wars movies (with better thumbnails than the un-viewable, tiny thumbnails on the artist's site).
There is a slide show gallery of large images at StarWars.com:
