It says Super 8.
Yup, lots of folks had 8mm cameras in early 60’s.
A few had really nice 16mm. There are great 16mm shorts shot by Roddy McDowell at his Malibu beach house in the early 60’s that are on youtube.

If it’s on Super 8 film from the 60’s and prominently features lady parts, Ann Dunham wouldn’t be the worst guess.
We had just bought a “standard” 8mm film camera in 1961, and I don’t think “super” 8 came out until a few years later.
A quick check of Wikipedia shows that “super 8” mm film was introduced by Kodak in 1965. The film came in cassette form (eliminating a truly major error-prone hassle changing film in the standard 8mm camera, twice per roll!). Also, the cameras and projectors featured larger film gates and image masks.
