There’s a storm brewing in Paris. Soaring temperatures at the Palais de Tokyo forces the art gallery by the Seine to shutter when it hits 35 degrees Celsius (95 Fahrenheit). To upgrade its climate control system, it needs an extended period of closure.

And here’s the rub: in 2027, the institution plans to decamp south to the 14th arrondissement and its prefered temporary home is La Générale, a 1930s building that has been an artist-run space since 2019.

Sébastien Jamain, a volunteer at the space where 150 artists work, told the French newspaper Libération that he recently met someone from the Palais de Tokyo measuring up their building.

A petition supporting the artists possibly made homeless by La Générale's takeover has been signed by more than 1,400 people. In a statement the Palais de Tokyo said it “would be open to dialogue”.

The amount André Abdoune paid for The Journey of Humanity by Sacha Jafri at a charity auction in Dubai. Five years later, the artist still has the giant canvas, charities including UNICEF have not received the money, and the “crypto billionaire” faces questions.

There’s only one painting attributed to Leonardo da Vinci hanging in a US museum, so you would have thought the arrival of a second one would be worth shouting about.

Instead, the Metropolitan Museum of Art quietly hung Madonna of the Yarnwinder months ago, and it was only this weekend that eagle-eyed dealer Evan Beard posted about it on Instagram, which ARTnews then reported.

Beard was strolling through room 609 when he spotted the small painting, which is on loan from the billionaire Ken Griffin. “No gawkers. No clout seekers. Just Leonardo radiating blue,” he wrote, sounding bemused by the lack of publicity.

The only painting by the Renaissance artist in a US museum's permanent collection is his portrait of a young female aristocrat. Ginevra de’ Benci has been in the National Gallery of Art since 1987 when its arrival in Washington was front-page news.

It seems some at the Met are in the dark about its da Vinci loan. After seeing Beard's Instagram post, Steve LoPiccolo asked someone at the main desk where he could find the painting. He said he was "assured that there was no Leonardo in the museum".

It's a great time to build your art library and save money.

LA gallery Regen Projects' summer book sale is underway, with publications on artists from Doug Aitken to Lawrence Weiner heavily discounted.

Magnum Photos’ self-styled warehouse sale is in its final days and hard to miss if you follow the agency on Instagram. Books, posters, and editioned images are on offer, including works by Martin Parr and Cornell Capa, among others.

New York's Matthew Marks recently held its summer clear-out, and it ended last Friday, but at the end of September, Printed Matter’s New York Art Book Fair (NYABF) returns. Ideal for collectors of artists’ books, independent publishing, zines, and experimental art publications, the fair runs September 24–27 at MoMA PS1 in Queens.

1- A catalogue raisonné of Jasper Johns’s prints (1994–2021) has been published by Universal Limited Art Editions. MoMA director Christophe Cherix has written the foreword and been closely involved in the project.

2 - The founder of Lubov in New York has died suddenly at the age of 37. Francisco Correa Cordero opened the gallery in a second-floor unit in Tribeca in 2016, before the area became a blue-chip gallery neighborhood.

3 - A Catherine Opie retrospective heads to the Royal Scottish Academy in Edinburgh, featuring more than 80 works by the LA-based artist. It opens on August 8 in time for the Scottish capital’s international arts festival.

4 - The White House wants to cut the Smithsonian’s funding, reducing it to levels not seen in a decade. The proposal could see staffing reduced by about 6% as President Trump increases pressure on the institution he claims is not patriotic enough.

5 - The director of the Guggenheim Abu Dhabi will be Valerie Hillings, who will move from the North Carolina Museum of Art to take the helm of the Frank Gehry-designed museum opening in December.
