Well before the Muppets Jim Henson was in the ad game.
From 1957 to 1961, Henson made 179 commercials for Wilkins Coffee and other Wilkins products, including Community Coffee and Wilkins Tea.
The bizarre and violent ads starred the cheerful Wilkins (Kermit pre-cursor), who liked Wilkins Coffee, and the grumpy Wontkins, who didn’t. And paid the ultimate price.
The characters proved so popular that in October 1958, the company offered vinyl puppets of Wilkins and Wontkins through the mail for $1.00 and a coffee can label.
The ads were well ahead of their time. Just think of the competitors ads at this time – housewife and husband etc
These are well worth a look.
