This outdoor ad in Germany is the best use of three billboards in a row since I was 10 years old, when we drove through South Dakota in greater anticipation of a drug store than Anton Chigurh did in No Country for Old Men. When we finally got to Wall Drug, it was a bit of a letdown, but I did get a fake snakeskin wallet and a postcard of a jackalope.
This is a wonderful example of using media to it's fullest advantage. Makes a point, makes it in a fresh, extremely, highly memorable way. Did I mention that it's memorable?
