Hip-hop mogul Jay-Z is launching his first book on November 16th, "Decoded" in a sort of scavenger-hunt way, with pages of the book hidden in places that are meaningful to the man, including the bottom of the pool of the Delano hotel in Miami and underneath plates at the Spotted Pig in NYC. Clues to their location were revealed on Jay-Z.com, a dedicated Bing site, and Jay-Z's Facebook and Twitter pages—and discoverers win prizes along the way. On Thursday, Gucci revelaed that two pages of the book were located in the windows of its Fifth Avenue flagship, printed in the lining of a leather bomber jacket. Hova superfans—don't get your hopes us. When the book is released, the jacket will be gifted to Jay himself. (WWD)
