A banana, duct-taped to a wall went on a sale at Art Basel Miami Beach this week — priced at $120,000. And, according to art market website Artnet, two of the three editions have already sold, with the last now going for $150,000. 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. It is Cattelan’s first contribution to an art fair in 15 years, according to the gallery.
