Also I think the PT posters are great. Come on, who didn't expect something great when they first saw that Phantom Menace trilogy? Of course we were all disappointed, but I for one still expected something great when I first saw the AotC poster, and I was again disappointed. When I first saw the ROTS poster it was hard for me to take it seriously with the goofy images of Palpatine and Padme. I didn't expect greatness from it at all, and yet I was still sorely disappointed.
One other detail on these posters I find perfect, is that though they are all by the same artist, the PT all say EPISODE in large writing, while the SE all say their names, notice how it is even called Star Wars instead of ANH. I think this signifies the lack of continuity between the two trilogies.
