The logo on this first poster was a popular alternative to the one seen nowadays. I still dig it.
Another cool poster with a totally different logo:
A foreign edition poster where Luke and Leia look even less like Hamill and Fisher than the various American posters.
These last two are drafts of poster art undoubtedly done well in advance of actual production. I love how they capture that 70's sci-fi paperback art look.
