Hirst has dared collectors to join him in his global conquest. With “The Complete Spot Challenge,” he has offered a prize, Willy Wonka style, to those who visit all 11 galleries worldwide—New York, Los Angeles, London, Paris, Rome, Athens, Geneva and Hong Kong. Confirm that you’ve visited all venues and he’ll sign a spot print dedicated to you personally. The average cost for this sort of quest… $13,000! Not a bad value considering the major press if you would get if you actually won and the grand prize itself. On top of this, ArtSpot will award you with a brand new iPhone 4S if you spot a spot painting at each location using ArtSpot!
