Guess which artwork is set to become the most expensive in the world?

But this is taking it to the next level: Picasso's Women of Algiers will be auctioned at Christie's in New York on Monday May 11, with experts estimating it will sell for around $140 million - making it the world's most expensive artwork sold at auction.

Instantly recognisable, the abstract oil painting is one of 15 in a series Picasso completed between 1954 and 1955. Like many of his works, it was inspired by one of the Old Master paintings - in this instance, Eugene Delacroix's 1834 work of the same name.

The price of fine art is said to be on the rise, with dealers attributing the boost to a renewed interest among both art aficionados and those new to the scene.
