Banana duct-taped to the wall

I know we are experiencing high prices but I am confident that I can find a banana for less than 6 million dollars.  The Italian artist Maurizio Cattelan contributed an art exhibit to a French museum consisting of a real banana duct-taped to a wall.  Of course, a real banana aged into rot over time but museum staff replaced the rotting fruit with a fresh banana as needed.  I read that the purchaser of the artwork got a certificate of authentication and a booklet explaining the process of buying a new banana and tape.

The web shows photographs of the art work.  As far as I have heard, eating artwork is unusual, rare even.  This reminds me of my friend who collects rare books and my other friend who delights in writing the author’s name in handwriting on the cover page of a book.
