nice! there's a similar type of ad here in Toronto on buses for some bankruptcy firm that show famous people and the date they filed for bankruptcy. I can't remember any of the specific ads (and am too lazy to try to google it), but was people like thomas edison, paul revere, etc.
good idea, IMHO to show that success is not only a destination, but also a journey...
as the say, if you get rich quick, its luck, but if you get rich and stay rich, its skill.. (dunno who said that, maybe i made it made up, but sounds good to me).
