Cool Idea, Annoying Execution

These ads were outside of a club I was heading to Friday night. The idea is to find two cars that are the same on each sheet (or at least that's how I was playing the game, I had a few shots beforehand). The silver cars are supposed to be scratched off like instant lottery tickets, but are just as annoying as instant lottery tickets. They don't scratch off very well at all, so it takes about 3 hours to uncover a whole car. Because of this, people give up, leaving the cars half scratched and the cars just end up looking vandalized. That's exactly what I want for my new car campaign; images of it to be plastered all over the city, keyed and scratched and looking like hell.
