In case you were wondering what the latest word is with Mauro Cavalletti, the former Mullen chief digital officer and current JWT Brazil chief integration officer, the exec has filled us in on some interesting work for Coca-Cola. Specifically, Cavalletti and crew at Group JWT, which includes JWT’s Sao Paulo branch and local units Casa and iCherry, have launched a new print effort to hype Coke’s online radio platform Coca-Cola FM on their home turf. With the FM platform turning a year-old, Group JWT decided to turn the cover of Brazilian teen magazine Capricho into a loudspeaker for the iPhone. We knew the numerous covers of the Twilight cast and other teeny-bop faves served a better purpose. Check out some of the print images after the jump, which may also explain things, along with Portuguese-infused credits you can pretty much figure out after the jump.
