It’s the iSpy Levi’s Twitter Campaign Case Study from their innovative social play earlier this year. Levi’s sent out hand selected people in their signature jeans across Australia and New Zealand while clues were released through twitter as to their whereabouts, after following clues through out the day, all you had to do was ask the person if they were wearing Levi’s… if you were right, they dropped their pants and gave you the jeans on the spot! Very cool.
