Jay-Z has recently brought out a new autobiographical book for rhymes and poetry / lyrics, named ‘Decoded‘. For the launch, Bing and the Droga5 agency made an amazing interactive marketing campaign in the form of a treasure hunt. Extracts of the book were placed all over the world. Depicted in underground stations, poolside loungers, bikes, plates and loads of other places. Check out some below or head over to the Bing page where you can see the full promo.
