Art collection expected to fetch at least $600m to help settle divorce

Macklowe collection includes works by artists including Picasso, Rothko and Giacometti

It is a collection that has attained almost mythical status in the art world, one that contains spectacular works by Picasso, Rothko, Warhol and a nightmarish Giacometti sculpture of a Pinocchio-like nose in a cage.

After a US judge ordered its sale to help settle a billionaire couple's acrimonious divorce there has been a string of rumours and stories about who would sell the collection and when.
