OK, with that I'll go off on a tangent.
One of the urban legends surrounding Star Wars when I was growing up was the recurring story of the friend of a friend who had the poster with the title of "all 12" of the Star Wars movies on it. I'm pretty sure this one cropped up in the lead up to Empire, and endured through a few years after Return.
The story was there was a poster released directly after Star Wars completed it's original theatrical run. This poster was nothing but the titles/logos for each of the movies in the Star Wars saga. The friend of a friend had purchased it through mail order from Lucasfilm.
Ironically, there just needs to be one more Star Wars movie for this poster to be actually possible. It would be a really boring poster with just 12 logos on it, but the child inside me really wants to see it become a reality.

My absolute favorite Return of the Jedi movie poster is the lightsaber poster: the hands holding up the blue lightsaber triumphantly/defiantly against a backdrop of space. A few years ago I realized it was by the same artist who did the Star Trek: The Motion Picture "rainbow" poster (another favorite), which makes a lot of sense.
