The dance of shadows: When museums release their treasures

01The fleeting eternity of collections

Museums are not immutable sanctuaries. Their walls, however thick, sometimes allow pieces to slip through that seemed destined for eternity under the spotlight. Take the Metropolitan Museum of Art. In 2021, it parted with a Degas, Dancer Adjusting Her Slipper, after sheltering it for ninety-two years. The pastel, breathtaking in its delicacy, depicts a ballerina in a stolen moment of grace—an instant when the body, freed from the public gaze, bends to the intimacy of preparation. Why part with it? Because the Met already owned seventeen similar works by Degas. Because museums, like human beings, must sometimes make painful choices to survive.

This practice, known as deaccessioning in museum jargon, is not new. As early as 1856, the South Kensington Museum—the precursor to the Victoria & Albert—sold "duplicates" to fund new acquisitions. But it was in the twentieth century that the phenomenon took on a nearly tragic dimension. During the Great Depression, the Art Institute of Chicago sold off Rembrandt and Van Gogh canvases to pay its bills. More recently, in 2020, the pandemic accelerated the trend: the Met divested itself of forty works, including a Monet and a Rodin, to plug a $150 million deficit. Museums, those guardians of memory, sometimes become unwilling merchants.

02The market of wandering souls

When a work leaves a museum, it does not simply enter the auction circuit. It becomes a wandering soul, laden with a history that transcends its mere materiality. Picasso’s Seated Woman is the perfect example. Painted during the Occupation, this canvas in shades of gray and blue carries within it the shadows of war. Dora Maar, the muse depicted, appears as a figure of melancholy—her face distorted by Cubism evoking both personal and collective suffering. When she leaves the Guggenheim, she takes with her the whispers of visitors who, for decades, paused before her, fascinated or unsettled.

The market has well understood the value of these narratives. A deaccessioned work often sells for 20 to 40 percent below its "normal" market value—but it offers something galleries cannot: museum provenance. Imagine hanging in your living room a Monet that graced the walls of the Musée d’Orsay for half a century. Or a Warhol that inspired generations of visitors at the Baltimore Museum. These pieces are not mere decorations; they are fragments of history you invite into your home.

03The invisible hands of fate

Behind every sale lies a complex decision, where ethics, finances, and sometimes ideology intertwine. In 2020, the Baltimore Museum of Art sparked outrage by announcing its intention to sell three masterpieces—a Warhol, a Brice Marden, and a Clyfford Still—to fund acquisitions of works by Black and underrepresented artists. The plan, ultimately abandoned under pressure, raised a fundamental question: should museums shed their past to build a more inclusive future?

This tension between conservation and renewal runs through the entire history of deaccessioning. In the 1980s, MoMA sold a Braque to buy contemporary works. In 2018, the Berkshire Museum parted with forty pieces, including a Norman Rockwell, to finance its renovation—a decision that led to its expulsion from the American Alliance of Museums. Each time, the same question resurfaces: how far can one go in the commodification of art without betraying its mission?

For collectors, these debates are a boon. They create opportunities, but also pitfalls. A work deaccessioned for ideological reasons—such as those some European museums might cede as part of the decolonization of their collections—may see its value fluctuate with controversy. Conversely, a piece sold for purely financial reasons, like the Water Lilies Monet divested by the Musée d’Orsay in 2019, represents a more stable investment.

04The melancholy of farewells

There is something profoundly melancholic about these sales. When the Everson Museum of Art parted with its Red Composition by Pollock in 2020, a piece of abstract expressionism’s history left the walls of Syracuse. The canvas, painted in 1946, marks a pivotal period in Pollock’s work—when he transitioned from recognizable figures to pure abstraction. The visitors who had contemplated it for seventy-four years would never see it again. In its place, the museum acquired works by Black artists and women, as if to redress a historical omission.

This melancholy is palpable in auction rooms. Auctioneers know these pieces are not mere objects; they are fragments of collective memory. When Seated Woman was presented at Sotheby’s, the catalog mentioned with a touch of nostalgia: "Formerly in the collection of the Solomon R. Guggenheim Museum." Those few words were enough to drive up the bids. Collectors were not just paying for a canvas; they were paying for the privilege of owning a piece of history.

05The collector as the new guardian of memory

Acquiring a deaccessioned work means taking on an unexpected role: that of a temporary guardian of heritage. You will not be the eternal owner of this canvas—history teaches us that private collections often return to the public fold, through donation or resale. But for the time it belongs to you, you will be its custodian. You will have to ensure its preservation, respect its history, and perhaps even share it with the world.

This is what makes these acquisitions so singular. They are not mere financial investments. They are almost philosophical acts. When you buy a Degas deaccessioned by the Met, you do not just own a pastel; you possess a part of the museum’s soul that once sheltered it. You become a link in a chain connecting the nineteenth century to today.

06The pitfalls of the shadows

Yet this market is not without dangers. A museum provenance can hide shadows. Some works are deaccessioned for the wrong reasons: conservation issues, doubts about authenticity, or even past looting. In 2019, the Musée d’Orsay discreetly sold a Monet without consulting the public—a decision that raised questions about institutional transparency. Before buying, one must dig, verify, and surround oneself with experts.

Fakes are another threat. In 2018, a canvas attributed to Modigliani and sold as deaccessioned by a small Italian museum turned out to be a crude forgery. X-rays and chemical analyses then become indispensable allies. A deaccessioned work must come with a detailed condition report, a certificate of authenticity, and, if possible, a complete exhibition history.

07The art of choosing your fragment of history

How, then, to navigate this market where every piece tells a story? First, by understanding that not all deaccessioned works are equal. A Monet Water Lilies, even in poor condition, will always hold more value than a nineteenth-century academic landscape. Established artists—Picasso, Warhol, Rothko, Monet—offer relative security. Their works, even deaccessioned, retain a safe-haven value.

Next, by favoring pieces with a strong history. Picasso’s Seated Woman is worth more for its past at the Guggenheim and its connection to Dora Maar than for its artistic quality alone. Similarly, a Warhol deaccessioned by the Baltimore Museum will gain value if the museum communicates the reasons for the sale—especially if those reasons relate to contemporary issues like diversity.

Finally, by accepting that these acquisitions are bets on the future. A work deaccessioned today could become a masterpiece tomorrow. In 1995, the Brooklyn Museum sold a Degas for $12 million—a colossal sum at the time. Today, that same canvas would likely be worth twice as much. The art market has this peculiarity: it rewards those who can see beyond immediate trends.

08When the work chooses you

There is something magical about these acquisitions. Unlike purchases in galleries, where one chooses a piece for its aesthetics or investment potential, deaccessioned works sometimes seem to choose us. They arrive laden with a history that resonates with our own. Perhaps this is why collectors who venture into this market speak of them with particular emotion.

One day, at a discreet auction in London, a Blue Nude by Matisse left the reserves of Tate Modern. The canvas, painted in 1952, depicts a reclining woman in an explosion of pure color. It had almost never been exhibited, as if the museum had forgotten it in a corner. Yet when it appeared on the market, it sparked immediate enthusiasm. The bids climbed, climbed… until a private collector won it for £35 million. Later, he would confess: "It wasn’t me who chose this Matisse. It was him who chose me. He was waiting for his moment."

Perhaps this is the true secret of deaccessioned works. They are not mere collectibles. They are living beings, charged with memory, patiently waiting for someone to understand them again. And when they find their new home, they bring more than beauty: they bring a part of the world’s soul.
