Obviously you're not THAT old school a jedi, as you nick claims ;)
As you must know the original German crawl to Empire HAS that typo. Even more: I am using the actual film transfer of that crawl (the Empire crawl isn't re-created by me... only the logo and the background were replaced by me), as it was used in the German HDTV broadcasts.
And since I've tried to re-create the classic German crawls, both that typo and the "belated" German logo for SW are included in these re-creations.
Yes, the first time I had the chance to watch ESB was when it first came out in the video rental shops on video 2000 back then. I think it was in 1982 or 1983. It was so long ago, that I cannot remember how the crawl looked.
I have several other releases on VHS but I don't have a player anymore so I cannot compare anymore.
