Chicago's Museum of Contemporary Art (MCA) will hope Sotheby's star auctioneer Phyllis Kao will bring some of her TikTok traction to their next fundraising sale.

Kao, vice-president of Sotheby's New York, was dubbed 'the viral auctioneer' last year after footage of her selling a dinosaur skeleton racked up almost 4 million views on the social media site and brought the auction house 30,000 new TikTok followers.

She will wield the gavel at the museum's auction on June 6 with donated works by artists including Ed Ruscha and Rashid Johnson up for sale with all proceeds going to support the museum.

Johnson's work Untitled Standing Broken Men is valued at $1.2 million, while Ruscha's Yup Nope should fetch $850,000.

British artist Thomas J. Price's Times Square takeover now extends to the billboards above the New York landmark.

His monumental sculpture, Grounded in the Stars, shows a 12-foot woman towering over passing New Yorkers in the square and is now joined by a series of stop-motion animations on more than 90 billboards.

The animations will run nightly from 11:57pm to midnight throughout May. Price also currently has more of his monumental bronze figures on show at Hauser & Wirth's Wooster Street gallery in the city.

Tributes have been paid to photographer John Humble whose pictures captured the "odd, mundane and everyday aspects" of life in Los Angeles.

His death was confirmed by gallerist Craig Krull who said his pictures were the result of "a long love affair with photographing Los Angeles".

Krull said the 81-year-old had been ill for a while but "made sure that he finished printing 25 photos for his next exhibition" before his death.

Humble was the subject of a major retrospective at the Getty in 2007.

There is a month to go before London's V&A museum opens its storehouse - complete with the chance to order an object from its vast collection for a closer look.

The storehouse opens on May 31 but visitors will be able to book the Order an Object service from May 13 giving them access to more than half a million works including dance costumes made for performance artist Leigh Bowery, ancient Egyptian shoes, Althea McNish fabrics and Lucie Rie ceramics.

Also going on show at the building in Stratford, east London, converted by architects Diller Scofidio+Renfro, is the 11-metre-wide stage cloth designed by Pablo Picasso for the Ballets Russes’ 1924 production, Le Train Bleu, which will be displayed for first time in more than a decade.

The artistic director of London's Serpentine Gallery Hans Ulrich Obrist will preside over the jury at this year's Venice Architecture Biennale.

He will be joined on the jury by Paola Antonelli, Director of the Department of Architecture and Design at Museum of Modern Art (MoMA) in New York, and South African architect Mpho Matsipa.

They will announce the winners of the Golden and Silver Lion prizes at an awards ceremony on Saturday May 10 when the exhibition opens to the public.
