This has me interested, so I've been scanning a few 70s era Fox titles. So far, the closest I've come across for Star Wars & ESB is from the American theatrical version of "The Leopard". The copy on the Criterion DVD isn't quite pristine (some film specs), but it's pretty good. Also note that the Star Wars Fox logos fade out early for the Lucasfilm logo. There are some other titles that you guys can check (Planet of the Apes, Poseidon Adventure, Towering Inferno, French Connection all come to mind), but I think I'll stop before I get obsessed.
