pace louise nevelson sculpture lawsuit 1234740585

Days before a Louise Nevelson sculpture was to be auctioned at Sotheby’s in May 2022, Pace Gallery founder Arne Glimcher declared the work inauthentic, claiming it was assembled by the artist’s son, Mike, rather than by Nevelson herself. The consigner, the estate of collector Hardie Beloff, has now sued Pace Gallery in US District Court for Eastern Pennsylvania, alleging that Glimcher deliberately sabotaged the sale to protect Pace’s control over Nevelson’s market. The lawsuit centers on Glimcher’s call to Sotheby’s, where he warned the work would not be included in a forthcoming catalogue raisonné, and on a 1993 appraisal in which he had valued the same sculpture at $85,000 without questioning its authenticity.

$102 Million Verdict Over Robert Indiana Artwork May End Years-Long Legal Battle

A Manhattan federal jury awarded $102 million in damages to the Morgan Art Foundation in its lawsuit against art publisher Michael McKenzie, finding him guilty of making and selling unauthorized Robert Indiana artworks. The verdict, delivered on April 23, follows a complex legal battle that began just before Indiana's death in 2018, involving accusations of exploitation, fraud, and copyright infringement. McKenzie and caretaker Jamie Thomas were also accused of taking advantage of the elderly artist. The case has cast doubt on the authenticity of some late Indiana works and affected his market, with his auction record remaining at just over $4 million since 2011.

Leonora Carrington, the British-born Surrealist artist, has seen a dramatic revival of interest in her work, with her paintings breaking auction records and her sculptures gaining new attention. However, a bitter dispute has emerged between supporters of her later bronzes and critics questioning their legitimacy, complicating her legacy. Carrington lived most of her life in Mexico and died in 2011 at age 94, but her reputation has soared posthumously, marked by a 2015 retrospective at Tate Liverpool, her influence on the 2022 Venice Biennale, and a current retrospective traveling from Palazzo Reale in Milan to Musée du Luxembourg in Paris. Her painting *Les Distractions de Dagobert* (1945) sold for $28.5 million at Sotheby’s New York in May 2024, setting a record for a British-born female artist, while her wooden sculpture *La Grande Dame (The Cat Woman)* (1951) fetched over $11.4 million in November 2024.

Turner, titled *The Rising Squall, Hot Wells, from St Vincent’s Rock, Bristol*, sold for £1.9 million ($2.6 million) at Sotheby’s Old Masters and 19th Century Paintings evening auction in London—more than six times its high estimate.

After cleaning revealed Turner’s signature, scholars confirmed its authenticity, and it was identified as Turner’s first publicly exhibited oil painting, exhibited at the Royal Academy in 1793. The winning bidder was a private collector in the U.K., outbidding Bristol Museum and Art Gallery, which had raised over £100,000 from donors in a failed attempt to acquire the work.

collector sues sothebys modigliani painting authenticity 1234762782

Collector Charles C. Cahn, Jr. has filed a lawsuit against Sotheby’s in the Supreme Court of the State of New York, alleging the auction house refuses to resell a painting attributed to Amedeo Modigliani that he purchased in 2003 for $1.55 million. The work, titled *Portrait de Leopold Zborowski* (1917), was consigned under a 2016 agreement allowing Cahn to resell it within 15 years, but Cahn claims Sotheby’s raised authenticity concerns and failed to respond to his recent attempts to consign the piece. He is seeking $2.67 million in damages.

conditional authenticity appraisal reports recent cases 1234743745

A Paris court seized 135 allegedly stolen paintings from Paris-based art authenticators ArtAnalysis in January, which had been holding the works for collector Mozes Frisch. The pieces are part of a 1,778-work collection supposedly by heavyweight Russian modernists. Palestinian businessman Uthman Khatib and his son Prince Castro Ben Leon claim the works were stolen from them by Frisch in 2019, and are suing in Germany for return of the works or $323 million. ArtAnalysis owner Laurette Thomas, Frisch, and collector Olivia Amar are countersuing Khatib for return of the Paris-held works plus $30.5 million in damages. The Khatibs' law firm Dentons hired Doerr Dallas Valuations to appraise the 135 disputed works, which assigned a $208 million valuation but included a caveat, likely related to the fact that many works were listed on the Art Loss Register in 2014 during an investigation into disgraced Israeli art dealer Itzhak Zarug, who was suspected of dealing fakes.

collector sues sothebys modigliani authenticity 2719506

Collector Charles Cahn has filed a lawsuit against Sotheby’s in New York Supreme Court, alleging the auction house reneged on a buy-back agreement made in 2016 regarding a Modigliani portrait he purchased in 2003. Cahn paid $1.55 million for *Portrait de Leopold Zborowski* at a Sotheby’s Impressionist and modern sale, and later agreed to consign the work back to Sotheby’s if he sold it within 15 years, with the house guaranteeing the greater of the original price plus 2.5% annual compound interest or the future sale price, and waiving vendor fees. However, Cahn claims that in April 2016, Sotheby’s own appraisal questioned the painting’s authenticity, stating it failed certain criteria and would have no sale value in the international art market. Despite Cahn’s letters in June and September 2024, Sotheby’s has not responded, leading to the breach-of-contract claim seeking at least $2.7 million in damages.

The Slow Death of the Contemporary Art Gallery

The article reports on the decline of the traditional contemporary art gallery model, driven by rising rents, changing collector behavior, and the rise of new artist categories. Tim Blum closed his Blum & Poe galleries in Los Angeles and Tokyo, citing systemic issues rather than market conditions. Art Basel and UBS data show the art market shrank overall but the number of sales increased, indicating a shift toward mid-priced works. Collectors are moving away from "blue-chip" artists toward "red-chip" artists who gain value through viral hype and cultural relevance, exemplified by Olaolu Slawn's accessible solo show at Saatchi Yates. Celebrities like actor Adrien Brody are also entering the market, though his work has been criticized as derivative. Meanwhile, smaller galleries like Tiwa Gallery, Landdd, and Marta are thriving by focusing on genuine connection, and retail spaces like Gentle Monster and Dover Street Market are blending art with commerce.
