Ads masquerading as columns were not something unheard of in newspapers. In many cases, they were labelled as an ad (in small print).
Here’s a blatant ad for Flintstones Vitamins pretending to be a news story about children’s health. It’s from the Carolina Times of February 28, 1970.
And, it’s just a wild guess on my part, but I don’t believe the artwork came from the Hanna-Barbera studio.
