The first audio print ad
This is the first time I see something like this. A plug & play print advertisement. To promote a music festival in Brazil, F/Nazca came up with the amazing idea of embedding an audio message on the cover of Playboy magazine.
A mini-chip has been inserted in the cover and users can listen to the an audio message (whispered by a young woman) simply plugging an headset in the jack.
One more way to make print advertising interesting and interactive.
