A banana, duct-taped to a wall went on a sale at Art Basel Miami Beach this week -- priced at around $120,000. And, according to the gallery behind the work, two of the three editions have already sold, with the last now going for even more. The work, by Maurizio Cattelan, was presented Wednesday by Perrotin, a contemporary art gallery founded in Paris that has had a long association with the Italian artist.
