Long-Hidden Blaquier Collection, Valued at $450 Million, to Be Auctioned at Sotheby's

A long-hidden private collection of Impressionist, Post-Impressionist, and Fauvist works will go up for auction at Sotheby's in New York on November 18. The group is valued at about $450 million.

A Collection Emerges

The collection comprises a dozen paintings from the estate of Nelly Blaquier de Arrieta and Carlos Pedro Blaquier. It is described as having remained out of public view.

The dozen works are valued at approximately $450 million and will be offered at Sotheby's in New York on November 18.

Carlos Pedro Blaquier is alleged to have been complicit in unspecified matters, a detail noted in the available material but not further elaborated. No additional facts about the allegations, the estate, or the consignment are present in the supplied source.

The sale brings together Impressionist, Post-Impressionist, and Fauvist works, three categories that have historically anchored the upper reaches of the auction market. The valuation places the group among the more significant single-owner offerings to be announced for the New York sales calendar.

Market Significance

For the auction sector, a collection of this scale and estimated value arriving on the block is a notable supply event. Long-held private collections that have not circulated publicly can attract institutional and private buyers seeking works with limited prior market exposure.

The timing, on November 18 in New York, positions the sale within the established autumn auction season. Sotheby's is the auction house handling the offering.

Specific artist names, individual estimates, provenance details, and the full terms of the consignment are not included in the available material. The absence of those details limits any assessment of how the collection's value is distributed across the twelve paintings.

The collection's valuation of about $450 million is the central financial figure disclosed. Everything else regarding the works themselves—attributions, conditions, prior exhibitions, or ownership history—remains outside the scope of the supplied information.

What Remains Unclear

The story is defined by what has been disclosed: a dozen paintings, a category range spanning Impressionism to Fauvism, an estate source, a venue, a date, and an approximate value. The rest—the specific works, their individual standing, and the outcome of the sale—is not yet part of the record.
