Sotheby’s Secures the $450 Million Blaquier Collection, Bringing Van Gogh, Cézanne, Degas, Renoir and Pissarro Back Into the Spotlight

A landmark Argentine collection is heading to Sotheby’s, in what could become one of the most consequential consignments of the 2026–27 auction season.

Sotheby’s has reportedly secured a major tranche of the Blaquier family’s celebrated Impressionist and Post-Impressionist collection, valued at approximately $450 million, according to people familiar with the transaction. The group includes important works by Vincent van Gogh, Paul Cézanne, Edgar Degas, Pierre-Auguste Renoir and Camille Pissarro, positioning the consignment among the most significant collections to reach the international market in years. The reported deal marks a major victory for Sotheby’s in its increasingly competitive battle with Christie’s for the world’s most valuable private collections. According to Artnet News, Sotheby’s offered a substantial guarantee to secure the Blaquier works, although the auction house itself declined to comment on the arrangement.

A Collection Shaped by Argentine Cultural History

The collection was assembled by Nelly Arrieta de Blaquier and Carlos Pedro Blaquier, whose holdings became synonymous with the highest level of private collecting in Argentina. In 1995, The New York Times described Nelly Arrieta de Blaquier as the owner of what was then considered Argentina’s largest private art collection. Her importance extended well beyond collecting. Arrieta de Blaquier served as president of the Asociación de Amigos del Museo Nacional de Bellas Artes in Buenos Aires from 1977 to 2011 and was subsequently named honorary president. Her death in 2020 marked the end of an important chapter in Argentina’s cultural and philanthropic history. The collection reflects the couple’s sophisticated taste for European modern art, with works by some of the defining figures of Impressionism and Post-Impressionism. Following the deaths of both Nelly Arrieta de Blaquier and Carlos Pedro Blaquier, their children are now overseeing the dispersal of a portion of this extraordinary legacy.

Van Gogh Could Lead the Sale

Among the most important works reportedly destined for Sotheby’s is Vincent van Gogh’s Châtaignier en fleurs roses et blanches (Chestnut Tree in Pink and White Blossom), painted in 1890. The work could emerge as one of the defining lots of the season. An art adviser quoted by Artnet News suggested that, in favorable market conditions, the painting could achieve between $150 million and $200 million. Its potential arrival at auction is particularly significant given Van Gogh’s extraordinary performance at the top end of the market. The Blaquier collection previously owned another celebrated Van Gogh, Zouave (1888), which was reportedly sold privately for approximately $190 million. Christie’s handled that transaction. The contrast is notable: a collection historically associated with Christie’s is now reportedly moving a substantial portion of its remaining masterpieces to Sotheby’s.

Cézanne, Degas, Renoir and Pissarro Complete a Blue-Chip Lineup

The reported Sotheby’s consignment extends well beyond Van Gogh. A major Paul Cézanne harlequin is expected to be among the highlights. Cézanne produced his celebrated Harlequin series around 1888–1890, and comparable works are held in major museum collections, including the National Gallery of Art in Washington, D.C. According to market sources cited by Artnet News, the Blaquier Cézanne could command more than $120 million. The collection is also expected to feature Edgar Degas’s Avant la Course (1893), a Parisian street scene by Camille Pissarro, and Pierre-Auguste Renoir’s En canot (ou Jeune fille à la barque) (1877). Each of these works could reportedly exceed $25 million at auction, underscoring the extraordinary concentration of high-value Impressionist material within the collection. This combination gives Sotheby’s something particularly powerful: not simply a collection of expensive paintings, but a coherent group spanning the transition from Impressionism to Post-Impressionism and illustrating the evolution of European painting in the late 19th century.

A Collection Already at the Center of an International Story

The Blaquier holdings have attracted attention beyond the auction market. Several works from the collection were previously exported from Argentina to Luxembourg under temporary authorization. Argentine Customs later imposed a substantial administrative penalty over the matter. Contemporary reporting valued the group of exported works at more than $350 million and identified paintings by Van Gogh, Degas, Renoir, Monet, Gauguin and Cézanne among them. According to Artnet News, the authorities ultimately waived the proposed penalty in July 2026. Some of the works involved are now expected to form part of the Sotheby’s consignment, although the precise composition of the sale has not yet been publicly confirmed. That uncertainty is particularly intriguing in the case of Claude Monet. Earlier reports identified two Nymphéas paintings among the works exported, one dated 1904 and another from 1908, with reported values of approximately $50 million and $42 million respectively. Sotheby’s has not confirmed whether either Monet will ultimately appear at auction.

Sotheby’s Makes a Strategic Move

The significance of the Blaquier consignment extends beyond the individual masterpieces. For Sotheby’s, securing a collection reportedly worth $450 million represents a strategic coup at a moment when auction houses are competing aggressively for scarce, museum-quality works. The market for top-tier Impressionist and Post-Impressionist art is increasingly driven by a limited number of paintings capable of attracting ultra-high-net-worth collectors from around the world. Sotheby’s decision to reportedly offer a significant guarantee demonstrates how valuable such consignments have become. The auction house is competing not only for individual masterpieces but for the opportunity to control the narrative around entire collections. The timing could also prove advantageous. Sotheby’s continues to promote its strength in Impressionist and Modern art, a category in which the house has a long-established history. Its catalogues regularly feature major works by Renoir, Cézanne, Pissarro, Degas and Van Gogh, illustrating the depth of its expertise in the period.

What the Blaquier Sale Could Mean for the Art Market

If the reported valuations materialize, the Blaquier collection could become one of the defining events of the upcoming auction cycle.

The most important question will be whether the market can absorb several exceptionally expensive Impressionist and Post-Impressionist works at once. A Van Gogh potentially valued at $150–200 million and a Cézanne potentially worth more than $120 million would already represent an extraordinary concentration of value. Add Degas, Renoir and Pissarro, and the collection has the potential to reshape the season’s hierarchy of trophy lots. Yet the importance of the Blaquier collection cannot be measured solely in dollars. Its story connects Argentine cultural philanthropy, European modernism, private collecting and the increasingly global art market. The dispersal of the collection will therefore represent not simply another auction, but the next chapter in the history of one of Latin America’s most important private art holdings. For Sotheby’s, it is a major acquisition of market share and prestige. For collectors, it may represent a once-in-a-generation opportunity to acquire works that have spent decades within a single distinguished collection.

And for the international art market, the message is unmistakable: the next great auction battle may already have begun.
