Now that’s thinking outside the box…
In Columbus Ohio, life — and apparently paint — comes at you fast. This eight-story advertisement for Nationwide Insurance required dousing an office building, a nearby parking lot and some cars in about 75 gallons of yellow paint, according to Orange Barrel Media, the ad agency that constructed it. The three-panel billboard proved one company’s willingness to take a risk on a prominent High Street building and another’s ability to carry out a client’s crazy plan.
Orange Barrel Media specializes in “Landmark Advertising” and has a handful of other brilliant projects pictured on their inspirational (yet, surprisingly slim on content) website: http://orangebarrelmedia.com/
