Heat-Sensitive Shipping Materials Double as DHL Ads

It seemed like worldwide shipping company DHL had pulled off an incredible advertising prank, by using other competitors shipping services and using heat sensitive ink to inscribe the words, ‘DHL is faster’ on the boxes. It turns out DHL had nothing to do with the trick, but they are certainly benefiting from the free publicity.
Well-known German ad agency Jung von Matt held an internal creative competition for its staff and the DHL prank was one result. To get around the fact that advertising campaigns can be expensive, Jung von Matt chose to use DHL’s competitors to do the heavy work. The agency created boxes that appeared black when cold — they were stored in walk-in freezers before being picked up — but then would slowly reveal the words ‘DHL is faster’ when they warmed in the carrier vans. Unsuspecting delivery men from competitors UPS, TNT and DPD all had to carry these awkwardly shaped boxes to particularly hard-to-reach locations, ensuring a lot of people saw the amusing message.
