Here is some “Truck Art”.  This 3-D artwork was produced for comercial 18-wheeler trucks in Germany. Here is the web site that the Truck Art (advertising) originated from The Rhino Award...  in Germany. They have a lot more of the same type of stuff on their web site...
The ads are printed on interchangeable canvas covers which are placed over the container portions of the trucks. In order to promote the new medium, RollAd sponsored an ad design competition, from which the images displayed below were taken.  The images displayed below are not real photographs, but digital mock-ups created for the competition.
