Patrick:
Here is a Koons that you may find interesting -

I wouldn't call it art but, yet, it was prominently displayed in a museum. That "sculpture" is two basketballs suspended in a tank of distilled water (couldn't run the risk of some microbes deteriorating the basketballs ?)
Or, how about a Damien Hirst spot painting that was done entirely by assistants following the design by the artist [?]. This went for more than a million dollars. The list could go on and on. These prices for contemporary art and how the prices evolved is the subject of the book. Incidentally, Hirst really did purchase a dead white shark, inject it with 224 gallons of formaldehyde for preservation and place it with a gallery that sold it for 12 million dollars.
This post rates more than a "keep smiling".
Laugh out loud
