In a very artistic advertisement, the following print ad was made by JWT for CADD, Community Against Drunk Driving, in India.
The artwork is very well done, but as messages go, it disappears in the art. By looking at the "motorcycle", made out of body parts, you can not see what it's about. It's only when you see the bottom tag line, "Don't let the drink drive you", that you understand what it is.
But then, maybe it works better in India...
They have two other ads like this, same artwork: Car Jeep
