# Knoedler and the Cost of Not Asking

> A gallery trading since the 1840s was closed by pictures painted in Queens. The Knoedler record shows the warning signs were commercial and arithmetical long before they were scientific.

## Key points

- The supply itself was the first red flag: unrecorded major Abstract Expressionist paintings arriving from one source at prices far below market, consistently, for years.
- Trial testimony put Knoedler's net income from the Rosales works at about 32.7 million dollars, with margins above 100 per cent and in places above 700 per cent.
- The provenance narrative changed under pressure, from an anonymous Mexican collector advised by Alfonso Ossorio to the dealer David Herbert, and the gallery's own archive search found nothing linking Herbert to the paintings.
- Glafira Rosales is the only person convicted; the gallery's former president was never criminally charged, has consistently said she believed the works genuine, and settled every civil claim without any court finding against her.

## The supply made no commercial sense, and that was the evidence



## The arithmetic was louder than the science



## The story changed, and the change was the tell



## Science arrived last and was decisive



## What ten lawsuits settled, and what they did not



The Knoedler affair is usually filed under science, because pigment analysis is what finished it. The record says otherwise. Every decisive fact was available in the gallery's own books and in its own correspondence years before a sample was taken: one source, no documents, prices that made no sense, a story that changed after a negative report, and a foundation putting its warning in writing in 2008. Diligence failed here at the point where somebody would have had to act on arithmetic they already had.

## Questions

**Was anyone at Knoedler convicted of a crime?**

No. Glafira Rosales, who supplied the works, pleaded guilty in 2013 and was sentenced in January 2017. No one at the gallery was criminally charged. Jose Carlos Bergantinos Diaz and the painter Pei-Shen Qian were indicted but never tried, having left for Spain and China respectively.

**How many forged works were involved?**

Prosecutors stated that Rosales sold more than sixty forgeries to two New York galleries for about 80 million dollars in total. Estimates of the number that passed through Knoedler alone start at about forty. The precise figure is not settled in the public record.

**What would have caught this before 2008?**

The commercial pattern. A single undocumented source supplying unrecorded major works at consistently below-market prices, sold on at margins repeatedly above 100 per cent, was visible in the gallery's own accounts from the 1990s. The technical analysis in 2008 and 2010 confirmed what the arithmetic had already implied.

**Do the settlements mean the buyers were made whole?**

The terms were not disclosed in any of the ten actions, so this cannot be stated. Separately, Rosales was ordered in July 2017 to pay 81 million dollars in restitution, but restitution orders against a defendant whose assets have been forfeited are not the same thing as recovery.
