I think it should be quite obvious that this is more of a nostalgiac aquisition rather than one to show off your A/V set up or to use for archival reference as far as differences picture wise. And as far as historical SW significance (other than the obvious mono soundtrack treasure), it is one of those things that old timers like myself remember as a "I know a guy who knew a guy whose uncle had a buddy who knew someone who had seen this at someone else's house one time back in '78". In the 80's it was one of the holy grail's of SW collecting. I heard about it for the first time in the early 80's and have wanted it ever since. It will sit on the shelf proudly with the other 40-odd SW discs in the collection.
