A Mondrian Painting Could Fetch $40.8 Million at Auction This Fall

The star of Christie’s 20th/21st Century Evening Sale in London on October 14 during Frieze Week is Piet Mondrian’s Composition III (1920). The work is coming to auction for the first time and is estimated to fetch between £20 million to £30 million ($27 million to $41 million).
Composition III (1920) arrives at auction by way of a private collector. The artwork was previously owned by American architect and collector of modernism Armand P. Bartos and his wife Celeste from 1952 to 1973.
“We are delighted to celebrate Mondrian’s extraordinary legacy and present his masterpiece from 1920, Composition III, in London, where another key work from this pivotal year resides, in the collection of the Tate,” said Keith Gill, vice chairman of 20th/21st century art at Christie’s. “Composition III dates from the breakthrough moment in Mondrian’s career, in which he reached a new, radical abstract idiom that profoundly reshaped the language of modern art. Appearing at auction for the first time in its history, it ranks among the most important and rarest of his paintings ever to come to market.”
The last time Christie’s had their hands on more than one piece by Mondrian was in 2009 from the collection of fashion designer Yves Saint Laurent and his business partner Pierre Bergé, which included Composition avec bleu, rouge, jaune et noir (1922) and Composition I (1920) selling for $27.9 million (estimated between $7 million and $10 million) and $9 million (estimated between $5 million to $7 million), respectively.
In 2022, Sotheby’s sold Mondrian’s Composition No. II (1930) at auction for $51 million in New York, a record sum for the Dutch painter’s work to date. In 2025, Christie’s sold the artist’s Composition with Large Red Plane, Bluish Gray, Yellow, Black and Blue (1922) at auction in New York for $47.6 million inclusive of fees from the Leonard & Louise Riggio: Collected Works sale.

The work is estimated to sell between £20 million and £30 million ($27 million to $41 million). The artwork is being offered by a private collector and was previously owned by American architect Armand P. Bartos and his wife Celeste from 1952 to 1973. Keith Gill, vice chairman of 20th/21st century art at Christie’s, noted that Composition III dates from a breakthrough moment in Mondrian’s career when he developed a new abstract idiom.

Full Take

The narrative centers on positioning a single work—Composition III—as an apex of Mondrian’s artistic evolution, leveraging its status as a first-time auction appearance to assign it immense rarity and importance among his oeuvre. The sequence of sales highlights a pattern where high-value works by the artist are successively monetized, establishing a high watermark for market perception. This process reinforces the narrative that certain historical moments in an artist's career possess disproportionate market value. The context of previous sales, such as those involving Yves Saint Laurent and subsequent record sales by Sotheby’s and Christie’s, sets up a pattern of concentrated historical importance being translated into financial valuation. The implication is that recognizing this specific moment (1920) grants unique authority over the broader artistic narrative, suggesting that value is not merely intrinsic but constructed through the framing provided by auction houses and collectors who situate the work within a perceived trajectory of genius. What assumptions are made about the relationship between historical breakthrough, market rarity, and ontological artistic worth in the context of high-end art sales? What mechanism ensures that subsequent artists’ breakthroughs receive comparable emphasis when entering the market?
