Here is a page from a Universal Campaign Book (circa 1978-79), which went out to television stations and showed their available films, with a focus on the early 1960's. It's printed on brown textured paper and hole-punched.
Interestingly, the synopsis on the back is very Kong-centric. This is somewhat understandable, because the failed De Laurentiis KING KONG was still fresh on people's minds (the text incorrectly refers to that film as being from 1977, and if we are being fair, the release date was December 17, 1976, so...almost.) But hey, we should be glad they didn't include the old fallacy about there being "different endings" of the film, right?
Another point of interest is the inclusion of one of the more unique of Toho's famous paste-up production photos, where we see Kong standing on a...uh, stadium? I've always wondered about that one.
Also, under "Starring," they list Kong and Godzilla (naturally, but they still give Kong top billing), and the only other names they bother to include are the "news presenter" actors who were added to the American version!
