Koff Beer INDIAN
Comment: This ad uses what appear to be Indians in Plains clothing. The main actor looks like David Midthunder, who was the only good Indian in Comanche Moon. I'm guessing the Indians are speaking Lakota or another Native language.
Other than the whole concept of naming a beer after Indians and using Indians to sell it, this ad is relatively innocuous. But that's a big "other than."
