Jim's Red Book "Cloverland Cow"
60-second Cloverland commercial.
Jim Henson produced an ad for Cloverland Dairy in Baltimore in 1965. Three versions of the ad were also produced -- one that was 60-seconds, one that was 20-seconds, and one that was 10-seconds.
In the commercial, "Sing a Song of Cloverland," a flat puppet cow dances through a moving farmland background, lip-syncing to a Cloverland jingle previously used in radio ads. The ad marked the earliest use of chroma key in Henson's work.
