Advertising Agency: Colenso BBDO, Auckland, New Zealand. "Maximum Ride is a series about a group of children who can fly. To launch the latest book, we created a large ground decal that showed Aucklanders what it was like to stand on the edge of a building and jump." http://adsoftheworld.com/media/ambient/maximum_ride_kids_who_can_fly?size=original
These trucks are a great example of how to push traditional advertising and make it something fresh and eye-catching. I think this might be concept work rather than actual ads, but the idea could be a great way to utilize semis, buses, and more.
