It seems that Ali, Boni, the wannabe Cub, and the photographer were all in Africa for a photo shoot to help the poor and downtrodden. Yes! I found the photographer's website, which helpfully explains:
For the Core Values campaign, both Ali and Bono wear Edun clothing. Ali carries a Louis Vuitton/Edun collaboration bag. This collaboration bag is a brown Keepall 45 in Louis Vuitton’s embossed Monogram Révélation leather. The bag is accessorized with a Monogram charm hand-crafted in Kenya by Made, a fair-trade fashion accessory company which strives to provide employment and promote ethical trade in Africa. Made regularly partners with Edun. Both the charm and the inside of the Monogram Révélation bag bear a plaque with the inscription “Every journey began in Africa.” Along with his guitar case, Bono carries a waterproof Keepall travel bag in Monogram canvas.Kinda makes your eyes water, don't it? How could any two individuals (well, three, counting the photographer) be so big-hearted? I feel like running right out and buying a Louis Vuitton billfold, or watch fob, or whatever they make in my price range. Blue skies! -- Dan Ford
