"The advertising firm of Doyle Dane Bernbach was responsible for one of Volkswagen of America’s most memorable advertising campaigns. Starting in the late 1950s and continuing at least through the mid-1970s, they were very unique and clever, so much so that VW has brought this advertising style back several times."
