The magazine that Margaret picks up from the coffee table while she looks for the missing picture of the Henslee family is titled "Hits." This periodical was more than likely a made-up prop for the show. Based on the front-cover headlines, it was probably styled on the likes of "Life" or "Look" that were popular magazines in the 1950s and '60s. There is a magazine called "HITS," but it is a trade publication for the music industry and was first published in 1986.
Stuart Erwin, who plays Mr. Henslee, was the star of his own TV series in the early 1950s: The Stu Erwin Show (1950).
