As Colin Gleadell points out below, the art world is waiting to learn where the Guston estate will move once the McKees retire from art dealing. Many say Hauser & Wirth will carry on having made some valuable sales for the estate over the past few years:

The first London exhibition for American artist Philip Guston since the Royal Academy show 12 years ago opens at the Timothy Taylor Gallery this week. Since David McKee, the New York dealer who represents Guston’s estate, has closed his gallery, this show has been organised independently of the estate, and will include the most expensive of his cartoon style late works, Head & Bottle, ever sold at auction ($6.5 million in 2007). Paintings that are for sale range from $125,000 to $5 million (£3.3 million).
