Ooh! $90m knocked off the value of a painting, just like that.
I must say, I know how Steve Wynn must have felt - just not on such a large scale.
When I was about 6 or 7 I accidentally knocked over a vase. The vase was on our TV and the water went down the back of the set. The resulting BANG and plumes of smoke meant no TV for the family for a day or two. And, presumably, no TV for me for a couple of weeks!
Okay, so our TV wasn't a work of art.
So, assuming that Mr Wynn decided to have a career change from Las Vegas property developer to freelance art destroyer, what single work of art would you want him to annihilate?
