1. JACKSON POLLOCK "Number 5, 1948", 1948 $140 million Private sale, 2006. Seller: David Geffen. Buyer: David Martínez (rumoured, denied by Martinez)
Right now, this stunning "drip" by Jackson Pollock is the most expensive painting ever sold, though the stunning price is still not confirmed (but also not denied). The exorbitant sum demonstrates not only the strenght of the Art market, but also the increasing interest for the contemporary works of Art.
Hope this helps!
