Three-time world heavyweight champion Muhammad Ali has joined Louis Vuitton's Core Values campaign. Photographed by Annie Leibovitz at his Arizona home, the shots see him watching one of his grandsons decked out in boxing gloves.

The print campaign rolls out from June 15, with a tablet version launching exclusively on June 13. Following on at the end of July, a video featuring rapper Yasiin Bey and graffiti artist Shoe launches, where they interpret in their own style, some of Muhammad Ali's immortal words.

The Cores Value campaign debuted in 2007 and aims to reinstate Louis Vuitton's legacy as the pioneer of the Art of Travel.
