Source: Communication Arts Design Annual November 2007This is an interesting ad. It's promoting Niagra Falls on a US mail box. The mailbox's curved surface is a perfect place for this ad making it look more real and more likely to catch the eye of a passer by. Even in your car you'll notice the waterfall. The only problem with this ad is the type is kind of small and it's near the bottom. Unless you had these on every mailbox in the city it'd be hard to catch the interests of people who are in their cars.
