The “Coming Summer 1990” is not included on the full screen R1 DVD box set.
It’s not in the 2002 Widescreen DVD set either. V1 or V2 (the original pressings of Part II and III had significant framing issues that were later fixed). It was restored for the first time on a video release (to my knowledge) on the 25th anniversary Blu-ray and DVD releases form 2011.
As a teenager I was a pretty die hard BTTF nerd for awhile after the first DVD set came out and I only came to know of the existence of the Summer 1990 tag from reading it on IMDB in the “alternate versions” section. I remember being impressed that it was restored for the Blu-ray. I had a whole bunch of computer printed BTTF crap hung all over my bedroom walls as a kid. I still have a book case with some of those images still taped to the side of it that I never bothered to remove, lol.
