The Spanish ad agency Leo Burnett Madrid has just created a new marketing concept. One of its members, Fred, has a tattoo of a QR code on the arm. Already unusual in itself, the initiative goes further, since the young man decided to turn his tattooed arm into advertising space via auction on eBay. Whoever gets the highest bid will have Fred’s arm for a month to advertise or display the content they want. The auction ends on April 29th.
