Mario Testino is recognized as the ultimate fashion photographer of his generation but his pictures of Kate Moss transcend fashion. The consequence of two decades of extraordinary friendship, and phenomenal glamor, this iconic collaboration is an intimate insight into the lives and minds of two of the world's definitive style leaders. Follow the journey of one of fashion's most extraordinary friendships, from early days backstage at the shows to behind-the-scenes glimpses of the ground-breaking editorials they continue to produce for the world's most respected magazines. Many photographs have been chosen from Testino's private archive and are published here for the first time.
