The third winner from Cannes 2010 that I like.

(click image, via) Am I getting soft (uh, NO)? Hey, this was a smart cheap little stunt performed by JWT London last December for their client Polo mints—it just won an outdoor gold lion. Taking advantage of a country-wide snow storm, agency creatives produced stamps that perfectly replicated the candy in snow, and hit the streets. You could argue that the total audience for the effort was low, but free media is free media. Previous Cannes 2010 winners that I like: one, two.
