Audio Print Ad in ‘Playboy’ Talks Up Brazilian Music Festival

We were just talking about the world's most innovative magazine ads, and here's another interesting one—an audio print ad for Brazil's Skol Sensation music festival, wrapped around the spine of Playboy magazine. A mini-chip was inserted in the ad, allowing users to listen to an audio message whispered by a young woman, says Adverblog. Nice work by F/Nazca Saatchi & Saatchi.
