Do you remember the name of an infomercial in the 1980s that featured a cardboard device that picked stocks?

It was obviously a scam, and there’s no way it could ever properly work. It was sold by a guy with wild dark hair who looked like he was in his 50’s. It was a cardboard sliding device that helped pick “buy” and “sell” days for particular stocks (probably based on past history, if anything at all). A decade later, an electronic device was being sold that did the same thing, but I’m asking about the cardboard device from the 1980s.
