It happened on the second-to-last day of the art show, where much fuss and head scratching this week has been over a solitary banana — an overripe one — duct-taped to a wall.

Three buyers paid between $120,000 and $150,000 this week for limited-edition pieces featuring a single banana, created by the artist Maurizio Cattelan and titled “Comedian.” Each came with a certificate of authenticity and replacement instructions, which perhaps should have included a disclaimer: for display only.
