Several of the older editions use original poster art elements. I'd go after some of the RCA CED's just for the cover art if I had the space.
There was a youtube video showing the differences in the AVTAK title sequence, (the full frame coming from a VHS) but it seems to be gone now.
I could kick myself for letting an old CBS/Fox Beta of FYEO go without checking it. I ended up with a lot of tapes chasing down that HBO Star Wars recording a while back.
Jumped on a factory sealed MWTGG only to realize too late it's full frame. Doh! At least it has digital sound. Not obsessed!
