This week, two stories about art and the long shadow of its history. A previously unknown archive from the doctor who cared for Van Gogh in his final days, and a New York court ordering the return of a Nazi-looted Modigliani worth as much as 30 million dollars. Then the verdict on Art Basel and the state of the British art trade a decade after Brexit.

A VAN GOGH DISCOVERY

We begin with a remarkable find. A previously unknown archive belonging to Paul Gachet, the doctor who cared for Vincent van Gogh in the last weeks of his life, has come to light, revealed this month by the Van Gogh specialist Martin Bailey in The Art Newspaper. The archive runs to more than 500 items: documents, photographs, letters, Gachet's own artworks, and family memorabilia, much of it catalogued by Gachet's son back in 1923. Its most important piece is a haunting one. It is Gachet's drawing of Van Gogh on his deathbed, dated the 29th of July, 1890.

A little background for anyone who does not know the story. Van Gogh spent his final months in the village of Auvers-sur-Oise, just north of Paris, under the care of Dr. Gachet, who was himself an amateur artist and a friend to the Impressionists. On the 27th of July, 1890, Van Gogh shot himself, and he died two days later. Gachet's sketch is one of only three known images recording the artist's death, which is what makes it so significant. For now, the owner, who wishes to remain anonymous, is holding on to the collection and has not announced any plans to sell or to donate it. But its mere existence adds new detail to the most heavily studied few weeks in all of art history.

A MODIGLIANI, RECLAIMED

Our second story is also about history, and about who gets to own it. After more than a decade in the courts, a New York judge has ordered the art dealer David Nahmad to return a painting by Amedeo Modigliani that was looted by the Nazis. The work is "Seated Man with a Cane," painted in 1918, a portrait of a chocolate merchant, and it is valued at as much as 30 million dollars.

The painting once belonged to Oscar Stettiner, a Jewish dealer in Paris who fled the city before the Nazi occupation in 1939, leaving his collection behind to be seized and resold. Nahmad bought the picture at a Christie's auction in 1996 for 3.2 million dollars, and it has sat in storage in Switzerland ever since. Ruling on the 16th of June, Justice Joel Cohen found that Stettiner, in his words, owned, or at a minimum had a superior right of possession of the painting, and never voluntarily relinquished it. Nahmad now has 30 days to hand the work to Stettiner's grandson, Philippe Maestracci, although his lawyers say they will appeal. It is one of the highest-value Nazi-era restitution rulings in years, and a reminder that provenance, the ownership history of a work, is not just paperwork. It can decide who owns a 30 million dollar painting.

ART BASEL, THE VERDICT

Now to the fair that has dominated the calendar. Art Basel has closed, with 290 galleries from 43 countries, and the verdict is cautiously positive. Dealers reported solid sales across price points, a relief after a couple of uncertain years, though it was the very top of the market that did the heavy lifting. The fair's biggest reported sale was a 1963 Picasso, The Painter and His Model in a Landscape, which carried an asking price of 35 million dollars at the gallery Hauser and Wirth, the same dealer that also placed a 20 million dollar Gerhard Richter and a 5 million dollar Cy Twombly. A sculpture by Yves Klein sold for about 2.5 million dollars at Xavier Hufkens. So the blue chips moved; the open question is everything beneath them.

BREXIT, A DECADE ON

That new shape is clearest in London, where The Art Newspaper this week took stock of Brexit's impact on the UK art trade, a decade on from the vote. The headline is that London has held on to its position as the world's second-largest art market, behind the United States, but its lead has narrowed. According to the art economist Clare McAndrew, the UK's share of global art sales has slipped from 21 percent in 2016 to 18 percent last year. The erosion is sharper in one of London's traditional strengths: its share of the European Old Masters market has fallen from 52 percent in 2014 to 38 percent in 2025.

The cause is less about demand than about friction. Leaving the European Union added layers of paperwork to the simple act of moving art across a border: import VAT, export licenses, and customs documents called ATA carnets. As Amanda Gray, a lawyer at Mishcon de Reya, puts it, gallerists and collectors have borne the brunt, in added cost, uncertainty, and delay. The effect has been uneven. The very top of the market is largely insulated, as a 200 million pound single-owner collection at Sotheby's this year showed, but the lower end has been squeezed hard. One number captures the institutional shift: the count of European Union galleries with a physical presence in London has fallen from eight in 2016 to zero today.

In this episode show notes

A Van Gogh Discovery

  • A previously unknown archive belonging to Paul Gachet, the doctor who cared for Vincent van Gogh in his final weeks, has come to light (revealed by Van Gogh specialist Martin Bailey in The Art Newspaper). It runs to more than 500 items, much of it catalogued by Gachet's son in 1923.
  • The most important piece is Gachet's drawing of Van Gogh on his deathbed, dated 29 July 1890, one of only three known images recording the artist's death. Van Gogh died in Auvers-sur-Oise on 29 July 1890, two days after shooting himself. The anonymous owner has announced no plans to sell or donate it.

A Modigliani, Reclaimed

  • A New York judge has ordered dealer David Nahmad to return Modigliani's "Seated Man with a Cane" (1918), valued at as much as 30 million dollars, looted from the Jewish Paris dealer Oscar Stettiner, who fled the city before the 1939 Nazi occupation.
  • Nahmad bought it at Christie's in 1996 for 3.2 million dollars. Ruling on 16 June, Justice Joel Cohen found Stettiner had a superior right of possession and never voluntarily relinquished it. Nahmad has 30 days to return the work to Stettiner's grandson, Philippe Maestracci, and says he will appeal. One of the highest-value Nazi-era restitution rulings in years.

Art Basel, The Verdict

  • Art Basel closed with cautiously positive results across 290 galleries from 43 countries, led by the top of the market: a 1963 Picasso ("The Painter and His Model in a Landscape") at a 35 million dollar asking price at Hauser & Wirth, plus a 20 million dollar Richter, a 5 million dollar Twombly, and a roughly 2.5 million dollar Yves Klein at Xavier Hufkens.

Brexit, A Decade On

  • London remains the world's second-largest art market behind the US, but its lead has narrowed. The UK's share of global art sales slipped from 21 percent in 2016 to 18 percent in 2025; its share of the European Old Masters market fell from 52 percent in 2014 to 38 percent in 2025 (Clare McAndrew, Arts Economics, in The Art Newspaper).
  • The cause is friction, not demand: import VAT, export licenses, and ATA carnet paperwork. The top is insulated (a 200 million pound single-owner collection at Sotheby's), the lower end squeezed. EU galleries with a London presence have gone from eight in 2016 to zero.
By the Numbers
ALT/FNDATA proprietary data
  • The very top of the fine-art market over the past year is a tight club. One Sotheby's sale produced a 10.1 million dollar Tamara de Lempicka ("La Belle Rafaëla"), a 9.6 million dollar Picasso, a 9 million dollar Basquiat, and a 7.7 million dollar Monet, all in one night.
  • The pattern: a firm top for trophy names with clean provenance, and a far choosier middle. That split is the story of the market right now.
