The viral artwork, involving a banana stuck to a wall, is once again in the spotlight, as Sotheby’s prepares to auction it for an eye-watering sum

Italian artist Maurizio Cattelan’s notorious installation involving a banana duct-taped to a wall is once again putting the slippery value of art in the spotlight.

This month, international auction house Sotheby’s will put one of the artwork’s three editions up for sale in New York, with an estimated price of between US$1m and US$1.5m. The successful bidder will receive a banana, a roll of duct tape, a certificate of authenticity and instructions on how to install the work.
