Sorry Sluggo I don't think I could get a picture, but it was basically this image:
with the roman numerals I, II, III (in gold lettering) and underneath IV, V, VI (in silver lettering) and the words "30th Anniversary" at the top of the poster. That's all it said. Nothing about what edition the films were, but it was obvious it was all 6 films and it was for the 30th anniversary.
I reckon its just a box set of previous releases, rather than re-edited versions, but that's just a guess.
