As a straight return on investment, it’s hard to beat “Untitled”, a 1982 work by Jean-Michel Basquiat, the African American street artist who became a global cultural icon, featuring a horned African mask on an abstract background across a canvas almost 5m wide.
In 2004, the painting sold for $4.5m. Back on the market 12 years later, it fetched $57.3m, then a record for a Basquiat. This week, it went under the hammer in New York for $85m (£68m), including fees, to a buyer from Asia.
