Internet/mobile advertising company, Adzookie, is offering to paint your home and pay your mortgage if you keep your house wrapped in their ad. Not a new idea, but this one will get much more attention for less marketing dollars than the cost of a traditional advertising campaign.
Any reason this concept will not work for your business or enterprise ? Wrap a car, a house, the bottom of an airplane. The possibilities are limitless. (But check the local zoning rules and regulations first !)
