It was used to illustrate a little story on Page 1 about candy sales being down in the United States or something like that. I just think it's fun to think about candy and candy machines from 1975, and I thought you might find it fun, too.
At the time, I'd've probably gone for the Baby Ruth or the Planters, but 2021 me really hopes 1975 me invests his 15 cents in a Bun, because I hadn't thought about a Bun in years!
Don't remember Big Shot.
