Orchard with Cypresses (1888), by the Dutch Expressionist painter Vincent van Gogh (1853–90), sold for $117,180,000 (£101,809,382) – including buyer's premium – at Christie’s in New York City, USA, on 9 November 2022 to an anonymous buyer. The painting was one of a series of 14 canvases depicting blossoming trees, which were created by Van Gogh a few months after his arrival in Arles, southern France.
Orchard with Cypresses was sold as part of a group of paintings and sculptures that had belonged to the late Microsoft co-founder Paul Allen. Their joint sale realized $1.5 billion (£1.3 billion) in early November 2022. Proceeds from the sale went to charities favoured by Allen.
