The first of David Hockney's celebrated double portraits is expected to fetch around $50 million at auction in New York in November.
The 1968 painting, recently featured in the Fondation Louis Vuitton exhibition in Paris, shows novelist Christopher Isherwood and his partner Don Bachardy.
It is one of only seven double portraits by the English painter with four of them in museum collections. The other two that have come to market are the most expensive Hockneys ever sold - Portrait of an Artist (Pool with Two Figures) went for a record-breaking $90.3 million in 2018, while the 1969 portrait of curator Henry Geldzahler and his partner Christopher Scott made $49.5 million a year later.
Isherwood, who was an English emigre to California like Hockney, made his name as a novelist. His Berlin stories form the basis for the musical Cabaret and his 1964 novel A Single Man was made into an Oscar-nominated film by Tom Ford.
The painting will be sold at Christie's 20th Century Evening Sale. The auction house announced today it will sell a collection of work from Japan's Kawamura Memorial DIC Museum of Art including pieces by Pierre-Auguste Renoir, Marc Chagall and Henry Moore.
The top lot is likely to be Claude Monet's 1907 Nymphéas which is expected to sell for around $40 million.
