The Hollywood Squares hadn't been on the air that long when host Peter Marshall landed an endorsement deal with Kellogg's. Here, Peter's doing some jogging to promote Product 19, which Kellogg's created to counter General Mills' Total. Sad to say, Product 19 isn't around anymore, but Total not only has survived, but has added additional flavors. Note that Peter didn't always wear his specs on the show. It was more of an on-again, off-again thing during the course of Squares' initial 15 year run (1966-81).
