Here's something I have hardly anything bad to say about.
(click image) It's an efficient idea for advertising fuel efficiency. To promote the new Volkswagen Golf BlueMotion, DDB in Berlin stamped the map portion of 5,000 Euro banknotes of various denominations with matching route lengths showing how far you could go for your money. The notes were put into circulation at German VW dealers and service shops. Yes, it is an example of Ad Creep, which I usually deride. But this defacing of banknotes isn't so evil. And it's informative (image via). Previously in VW ads: Classic. Sexist. Terrible. And zany (the Peter Stormare GTI spots).
