The British Museum is considering staying open all night to meet visitor demand for its Bayeux Tapestry show.

The Financial Times magazine reported "there has been talk of all-night openings", but said the French had to be consulted about how long it can be on display before any decision is made.

Peter Ricketts, Britain’s official Bayeux Tapestry “envoy”, said: "We have to protect the object and make sure that it goes back in the same pristine condition in which it arrives."

The London show, which will run from this September to next July, has caused controversy in France where previously planned loans were canceled over fears the 230-foot-long embroidery will be damaged while being transported and installed.

More than 78,000 people have signed a petition opposing the loan and earlier this year David Hockney branded the idea as "madness".

The museum in Bayeux, which is usually home to the tapestry that retells the invasion of England by William the Conqueror in 1066, is closed for renovation work until next year.

The total estimated value of works from the collection of the late art dealer Marian Goodman being offered at auction by Christie's in New York in May. Among them are seven Gerhard Richter paintings including his 1982 work Kerze (Candle) which is estimated to fetch up to $50 million.

A group of anonymous artists is filling in cracks in the sidewalks of Portland, Oregon, with tiny mosaics.

The Portland Tile Guerrillas said installing dozens of hand-cut tiles across the city was an attempt to fill "the city’s voids with color and connection".

They use their Instagram page to post images of new mosaics with clues to their location and even take requests - a tile with a Grateful Dead song lyric "If you plant ice, you’re gonna harvest the wind" was placed near a U.S. Immigration and Customs Enforcement facility after a fan asked them to do it.

The streets of San Francisco had a new visitor this week - a robot dog complete with a life-like version of Elon Musk's head.

The robot, which was seen in the city's South Beach neighborhood, was taken for a walk as part of a promotional push for a new show by digital artist Beeple in nearby Palo Alto at the NODE gallery.

It is one of a series of robot dogs he created and first showed in December at Art Basel in Miami, all of which have hyper-realistic heads resembling people including Musk's fellow tech entrepreneurs Mark Zuckerberg and Jeff Bezos.

The works, called Regular Animals, are part of the show opening next Saturday.

A gallery spokesperson told the San Francisco Chronicle the robots were "a physical embodiment" of digital culture, adding: "Sending Elon into the streets is a way to bring that energy into public life ahead of the exhibition opening next week, and the reaction has been exactly what Beeple’s work does so well: it stops people in their tracks and gets them talking."

American celebrity chef Rick Bayless has put his money where his mouth is and donated $1 million to Chicago's National Museum of Mexican Art.

The money from the Bayless Family Foundation will go towards the $5 million renovation of the west wing of the building which is based in a park in the city's Pilsen neighborhood.

Bayless, who made his name championing Mexican cuisine in TV shows and cookbooks, has served on the museum's board of trustees and said he was "honored" to help it "broaden its reach and community impact".

The museum, which was founded in 1982, includes works by the likes of Carmen Lomas Garza, Elsa Munoz and Diego Rivera.

1 - The Seoul Photo Festival has relaunched after five years away following its suspension during the pandemic. The festival, which will run every other year, is now managed by the Seoul Museum of Art and its director Choi Eun-ju and includes a photo walk linking 24 different venues across the city.

2 - The Getty Center in Los Angeles is closing on March 15 next year for around 12 months for what is described as "the most significant series of modernization initiatives since its 1997 opening". Katherine Fleming, president and CEO of the J. Paul Getty Trust, said the work which includes updating its hilltop tram system and renovating its Welcome Hall would be finished by Spring 2028 "in time to celebrate the Summer Olympic and Paralympic Games".

3 - A spiral staircase that was originally part of the Eiffel Tower is expected to sell for $176,000 at auction next month. The nine-foot-high staircase was part of a section removed from the Paris landmark in 1983 when elevators were installed.

4 - A new show exploring how artists in Philadelphia have explored the idea of America opens on June 20 marking the 250th anniversary of the Declaration of Independence. Arc of Promise, which will run at the city's Woodmere Art Museum until November 8, takes its name from a concept expressed by artist Jerry Pinkney who was born in the city.

5 - Italian art collector Patrizia Sandretto Re Rebaudengo's foundation is officially opening its third venue next month. The site on the island of San Giacomo in Venice offered visitors a first preview two years ago when Hans Ulrich Obrist curated a show by artist and choreographer Eun-Me Ahn.
