This campaign is something cool I discovered on Adverblog recently. It's a cool use of SMS from Axe Uruguay. To see the complete picture of the scantily clad model, the ad simply asked the reader to text Axe to a short code after 9pm (to keep kids away). You then get to see the scantily clad model in her full glory. This is a smart understanding of the Axe brand (which is called Lynx here in the UK), and a great demonstration of how SMS and print can work together.
