I had the fortune of seeing a 35mm print of American Graffiti at the New Beverly Cinema a few years ago in 2013/2014. Sadly the print included all of the Special Edition changes (colorful sky at the beginning, changed end card, etc.) and the 1978 re-issue changes.
A few years ago I was looking at buying a adapted scope 16mm version on ebay that was on LPP (not the one listed above), but ebay malfunctioned and my bid didn’t go through. Print went for around $160. 😦
I still wonder if that print was of the 1978 version…
