“What you buy when you buy Cattelan’s ‘Comedian’ is not the banana itself, but a certificate of authenticity that grants the owner the permission and authority to reproduce this banana and duct tape on their wall as an original artwork by Maurizio Cattelan,” Galperin said.
Wait. Let's review.
You provide your own wall, your own tape, and your own banana, and then you pay $1 million for permission to tape the banana to the wall and call it art.
Of course after not-many-days the banana will turn to mush and then do you have to pay another million to tape another banana to the wall? Do you have to use the same tape? Can you use the same wall?
Can you still call it art?
What about, say, a grapefruit?
