If at first you don’t succeed, try again. That motto has paid dividends for the owner of two sketchbooks he always believed belonged to Henri de Toulouse-Lautrec.

Eight years after a committee of experts declined to attribute the watercolors and drawings inside them to the French artist, Alain Brun, whose grandmother had kept the sketchbooks in a shed, has prevailed.

Brun assembled a portfolio of evidence assisted by the BBC TV series Fake or Fortune?, which revisited the disputed works in a new episode first broadcast yesterday, August 19.

Reversing its previous attribution to the artist's tutor, René Princeteau, the Comité Toulouse-Lautrec has now agreed that one of the sketchbooks is “authentic”, and that 25 works in the second book are by Toulouse-Lautrec, too.

Donald Judd was most specific about his specific objects, the name he preferred for his three-dimensional works. None more so than the 100 aluminum boxes he installed at his sprawling museum in Marfa, West Texas.

They are housed in the Artillery Shed of the former US Army base that Judd turned into the Chinati Foundation.

More than 40 years after the artist installed them, all 100 works will have to be moved so that the building can be upgraded. Alfred Lippincott, who was one of the works’ original fabricators, and the Getty Conservation Institute are providing expert assistance.

The two-year closure of the Artillery Shed is part of a $16.5 million project that also includes addressing the effects of soil erosion across the windswept site.

Judd’s ideas about how his and his friends’ art should be presented permanently were pretty fixed but he knew that some changes were inevitable. As the Artillery Shed heats up and then cools each day, his 100 aluminum boxes have shifted over the years, albeit imperceptibly. That said, temperature fluctuations within the building will be reduced when new high-performance glazing is installed.

Is there a doctor in the Giardini? Just in case there isn’t, The Netherlands has a medic on hand should a performer in its Venice Biennale pavilion require assistance or a health check-up.

The artist Dries Verhoeven told Frieze magazine three rotating performance teams are needed for his work, The Fortress, and there is “a doctor on board”. His work takes place daily.

The disclosure back in April prompted The Times to look into the challenges of staging live performances during the more than six-month-long biennale, which closes in November.

It found different levels of fatigue and frequency of performance. For example, Florentina Holzinger and colleagues perform Seaworld Venice in the Austrian pavilion in full only on selected dates. The work includes a female performer replacing the clapper of a church bell and a woman on a jet ski in the flooded pavilion. Both are naked.

Extreme performances are nothing new. In 2017, Anne Imhof won a Golden Lion for her German pavilion. It featured a daily two-hour-long performance of semi-clad human participants plus a pack of Dobermans.
