Director of New York's Metropolitan Museum of Art Max Hollein hailed Jeffrey Gibson as "one of the most remarkable artists of his generation" after his four huge sculptures were unveiled on the outside of the building.

Gibson's work - four 10-ft-high bronze sculptures of a hawk, a squirrel, a coyote, and a deer - will occupy the otherwise empty niches on the museum's Fifth Avenue facade until June 9 next year.

Called The Animal That Therefore I Am, the works are inspired by French philosopher Jacques Derrida’s book of the same name examining the relationship between humans and animals.

Previous artists commissioned to temporarily fill the niches include Wangechi Mutu, Carol Bove, Hew Locke, Nairy Baghramian and Lee Bul.

Sculptor Armand Vaillancourt has threatened legal action if San Francisco demolishes his huge brutalist concrete fountain which sits in the city's Embarcadero Plaza.

The work, which weighs 710 tons and stands 40-ft high, was unveiled in 1971 but the city's Recreation and Parks Department wants to remove it as part of a $35 million plan to redesign the area.

In a letter sent by his lawyers, the plan to remove it is described as "a wrongful and unlawful interference with Mr. Vaillancourt’s moral rights and with the cultural and public trust interests associated with his work".

They ask the city to "cease and desist from taking any steps whatsoever that may endanger or damage the Vaillancourt Fountain" and warn they will "pursue all available remedies provided by law" if the city fails to comply.

The work has long been controversial with one critic describing it as "Stonehenge with plumbing problems".

Painter Etsuko Nakatsuji has won the inaugural $10,000 Hana Artist Award at this year's Tokyo Gendai art fair.

A former graphic designer for an advertising firm, she had her first solo exhibition in 1963 and has also worked as a stage designer and book illustrator.

The fair, which opened to the public today and runs to Sunday, has attracted dealers including Pace Gallery and Sadie Coles and work by artists from Dylan Kraus to Lee Bae.

It is a yard sale like no other - Cindy Sherman is selling off the contents of her Paris apartment.

Her former home in the French capital, designed by Argentinian architect Luis Laplace, is being recreated across a whole floor of the Piasa auction house which is handling the online sale.

Among the 218 lots are ceramics, furniture, books, a portrait of her by Karl Lagerfeld and a Leica camera.

Also included are six chairs by Brazilian designer Guglielmo Ulrich estimated to fetch $10,500, a pair of glass vases by Massimo Micheluzzi valued at around $1,700 and pieces by artists including Rosemarie Trockel.

The sale is on October 2.

A multi-million dollar deal is being discussed that would see a French entertainment company buy the Swiss museum dedicated to the life and work of Charlie Chaplin.

Chaplin's World opened in the silent movie star's old home in Corsier-sur-Vevey nine years ago but has reportedly struggled in recent years with visitor numbers not recovering post-pandemic.

A statement from Museum Studio said it wanted to "strengthen the international reputation" of the museum and would look to build other sites around the world.

Born into poverty in south London, Chaplin became a worldwide star in the early days of Hollywood with his Tramp persona which was a huge influence on the Dada movement. He spent the last 25 years of his life in Switzerland.

The museum, which includes more than 4,000 sq ft of exhibition space, a film studios, reconstructed sets and archives, has had more than 1.5 million visitors since opening.

1 - The Paris-based European House of Photography is advertising for a new director after Simon Baker left the role after seven years. Baker was the Tate's first photography curator before taking charge of the French institution which was founded in 1978.

2 - Two is better than one for Los Angeles–based dealer Hannah Hoffman and New York’s Bridget Donahue who are merging their businesses to form a single operation. The new entity will keep its existing galleries on either coast and launch another in Beverley Hills later this month.

3 - A 98-ft tall tower unveiled in the Swiss village of Mulegns has set the record for the tallest 3D-printed building in the world. The concrete structure, which cost $5.5 million, is intended to be used as an immersive performance venue.

4 - Glenn Lowry has left the building. Among those paying tribute to the Director of New York's Museum of Modern Art, who left this week after 30 years in charge, was Frick Collection Director Axel Ruger who said it was the "end of an era".
