Jay-Z is released an autobiographical book titled “Decoded” ($35) that covers his life from a rough childhood to hip hop mogul. To stir up some buzz, Jay- Z teamed up with Microsoft through Bing for a scavenger hunt of select pages from his book, which were hidden in different cities around the world. Gucci participated in Jay-Z’s little game of hide and seek by creating an exclusive leather bomber jacket with two pages from the book on the interior lining.
