Francis Bacon's "Three Studies of Lucien Freud"

The Francis Bacon painting "Three Studies of Lucian Freud" was sold for a whopping $142.4 million as part of a $691.6 million Christie's sale on Tuesday night, making it the most expensive work of art ever sold at auction.

Some argue that the sale is giving us a message about inflation that investors aren't getting from the action in gold, the Dollar Index, or the government's official consumer price index data.
