There is a depressing sense of symmetry in the news from Thailand where it is reported an exhibition about authoritarian governments has been censored by an authoritarian government.

News agency Reuters first reported the Bangkok Arts and Cultural Centre was pressured by China to remove some works and alter others, including removing the words "Hong Kong", "Tibet" and "Uyghur".

Chinese embassy staff visited the gallery which, in an email seen by journalists, said it had "been warned that the exhibition may risk creating diplomatic tensions between Thailand and China" and that it had "no choice but to make certain adjustments".

The name of the exhibition? Constellation of Complicity: Visualising the Global Machinery of Authoritarian Solidarity.

The trend for museums making visitor attractions out of what was once seen as boring back office work has reached Iran.

A huge 3,000 kilogram bronze sphere sculpture by Italian artist Arnaldo Pomodoro is being restored by staff at the Time Museum in Tehran and the public are invited.

It is one of several works by Pomodoro in Iran which were brought to the country during the reign of the Shah including a miniature, 30-centimeter model at the Niavaran Palace complex.

The project to restore the work, which has spent almost 50 years on show outdoors in a park in the city, is expected to last more than three months and is taking place in a transparent, on-site workshop.

One of the most notable examples of the trend to let the public behind the scenes is the new V&A East Storehouse in London which is designed to allow visitors to see thousands of works normally locked away in storage or conservation workshops.

The number of unsold works by Pablo Picasso found in different studios and homes when he died aged 91 on April 8, 1973.

It is 100 years since F Scott Fitzgerald published The Great Gatsby - his immortal tale of a mysterious millionaire who dazzles New York's social scene before tragedy strikes. Which brings us to the strange story of Matthew Christopher Pietras.

The 40-year-old was found dead on May 30 - just a day after the city's Metropolitan Opera was told the $10 million he had just donated was not his to give.

It is reported Pietras worked as an assistant to Gregory Soros, a son of billionaire investor George Soros, and also Courtney Sale Ross, the widow of the Time Warner chief Steven J. Ross. The families are working together to discover whether their money was used to fund his cultural largesse.

The Met promptly returned the money while another of his beneficiaries, The Frick Collection, said it did not "believe that any of the contributions were made with misappropriated funds".

It is not clear how much Pietras gave the museum though the New York Times reports it was somewhere between $1 million and $4,999,999. But what is clear is it was significant enough for the Frick to name a position after him - the Matthew Christopher Pietras Head of Music and Performance.

This tiny carved bone figure of a bull spent 8,000 years lying undisturbed in a child's grave before it was discovered and put on show in a museum for another almost 100 years, but where it is now is a mystery.

It disappeared from the Mariupol Museum of Local Lore in Ukraine three years ago when the building was damaged and much of its collection lost or looted during months of attacks by Russian forces.

It is one of more than 1.7 million antiquities to disappear amid the Russian invasion and is the subject of a global alert from the Antiquities Coalition - topping its Ten Most Wanted list.

The coalition said it was last seen in photographs appearing in exhibitions promoting the Azov region, where it was first found, as historically Russian - raising concerns it is in Russian hands and being used to justify its territorial claims.

1 - A slice of Chicago history was brought back to life at the weekend when an inflatable model of the long-demolished Mecca Flats was unveiled on the site of the original building. The flats, demolished in 1952, were a central part of African-American life in the city and the inflatable monument is the latest in a series of lost buildings recreated by the Floating Museum art collective.

2 - Vancouver city council is looking for a new home for a 10-meter-high sculpture, Trans am Rapture, which shows five cars stacked on top of a giant tree trunk. A proposal to move the public artwork, by artists Marcus Bowcott and Helene Aspinall, was put on hold after people living at the planned site protested saying it would block their views.

3 - Tributes have been paid to art collector Sylvio Perlstein who died last week. Among those remembering him was Hauser & Wirth gallery which showed almost 400 works from his collection, including pieces by Man Ray and Richard Long, in an exhibition in 2018.
