I recently bought the Star Wars Omnibus: A Long Time Ago..., Volume 1, which has the first 26 issues of the 1970s Marvel comics.
I had a giant version of the original six issues that covered the original movie, as well as normal-sized copies of a few of the following issues.
Looking through it, it occurs to me that—in the days before we had a VCR—this was as much Star Wars to me as the movie itself. I only saw the movie once (until years later), but I read these comics over-and-over.
They even had deleted scenes...
