World's Most Expensive Painting

No.5, 1948 - This is the name of the world's most expensive painting, a photo of which you can see above. The painting was made by Jackson Pollock, an American painter and an abstract expressionist. The painting is an abstract painting and costed around $140 million, thereby making it world's most expensive painting. According to a news, another painting called "Blue Poles" by Jackson Pollock is worth atleast $180 million AUD and may cost even more than No.5 1948. 

As said, the painting is an abstract painting. I don't know what exactly is hidden in that, but I can say whatever it is, is really very well hidden and abstract from my eyes atleast. Feel free to give your insights and comments. I'd be delighted to discuss them here.
