Back in the day, when Dolly Madison was affiliated with Millbrook bread and not Hostess, the company mounted a modest advertising campaign to promote their Gems mini-donuts. Now, I have to tell you that I'm only seeing this ad for the first time today.
Character actor Fritz Feld is the "Gem-cutter". Robbie Rist (ex-The Brady Bunch) appears in the ad as well. The announcer is Michael Rye.
In my area, the Gems were pretty much pre-sold, if only because of ties to the Peanuts comic strip. Dolly Madison was a primary sponsor of the Peanuts specials that aired on CBS at the time. As memory serves, Charlie Brown appeared on the wrappers.
