No real non-film memories for me. Maybe it's because I was a little older in 1977, but I wasn't a toy person. For me it was just a few things hanging on my wall - the poster that came in the soundtrack album, the lobby card set, the teaser one-sheet, and the regular one-sheet. (I still have that teaser). I used to go to movie conventions and had a fair amount of film memorabilia in my room.
I played the soundtrack constantly. I made a cassette of it several months later because I had a driver's license by then and wanted a copy of it for my car. The score has always been a favorite of mine and it was a big part of the adventure for me, away from the theater visits.
Weirdly enough, not even t-shirts for me back then. That would later change and I would silkscreen my own regularly, but I never made a Star Wars shirt. I had already moved on to Raiders Of The Lost Ark by the time I started silkscreening.
