The number of Nintendo 3DS consoles returned by the Louvre to the tech firm after the end of the 13-year scheme that saw them used by visitors as hand-held multimedia guides to the Paris museum.

Two fragments of a painting believed to be by Lucas Cranach have been reunited after almost 90 years apart and gone on show together in a German museum.

The work, Salome with the Head of the Baptist, was chopped in two in 1937 by an art dealer who wanted to sell the top half as a portrait of a woman without the gruesome reminder of severed head from the bible story it was illustrating.

Both sections are now on show at the Ducal Museum in Gotha whose director of collections, Timo Trumper, said its return was "an extraordinary gain, for Gotha and for art historical research as a whole".

Another twist in the tale of the looted Nazi art recently unearthed in Argentina - its current owners are banned from leaving their house but it appears the painting already has.

Portrait of a Lady by Italian artist Giuseppe Ghislandi was spotted on the wall of a house belonging to Patricia Kadgien whose fugitive Nazi father is believed to have stolen it from Jewish dealer Jacques Goudstikker.

Kadgien and her husband Juan Carlos Cortegoso are now under house arrest by order of the Argentinian police after they failed to find the painting which was originally spotted by a sharp-eyed observer when it featured in a real estate listing.

It had been replaced by a tapestry by the time of a police raid and subsequent searches of other properties owned by the family failed to find it.

Kadgien is the daughter of Friedrich Kadgien, a financial advisor to Nazi leader Hermann Goring, who stole more than 1,000 works from Goudstikker including the Portrait of a Lady.

The lawyer in charge of the case says the couple have been accused of obstructing the investigation and will be under house arrest for three days.

The leaders of London's cultural scene love to boast about the city's free museums but for how much longer?

Free entry at major institutions including the National Gallery and the British Museum is government policy and a recent think tank report backed that, saying introducing fees for foreign tourist would be "detrimental and costly to the UK’s museum ecosystem and reputation".

But there are signs of support for a change amid pressure on public funding with the latest note of dissent coming from the head of London's Design Museum Tim Marlow who said he had changed his mind on the issue having originally been "vehemently against the idea of charging".

He told The Times of London: "But now you see coach loads of tourists with tour operators who clearly charge them a fortune going to [a museum] to see five things and then leaving."

Marlow, whose CV includes stints at the Royal Academy and White Cube, said he wants to move to the "good system" used in the Netherlands where residents have free access while overseas visitors pay.

Of course this scheme depends on a steady stream of tourists coming through the doors - something Marlow is presumably confident about as the Design Museum recently announced its Tim Burton show - which like all its special exhibitions is paid for - had become the most visited in its 35-year history.

A series of Tyler Mitchell photographs taken for this year's Superfine: Tailoring Black Style exhibition at New York's Metropolitan Museum of Art are going on show in London.

It is the first public display of the pictures which featured in his photo essay for this year's Costume Institute exhibition at the museum.

They can be seen at Gagosian's gallery in Burlington Arcade from September 15 to October 3 and are described by Mitchell as "a love letter to modern Black dandyism".

1 - The Independent 20th Century art fair opens in New York's Battery Maritime building tomorrow and runs until Sunday. The invitation-only event features 31 exhibitors and 40 artists with Elda Cerrato and Gertrude Greene among those whose work is featured.

2 - The National Gallery of Denmark is expanding - it just opened a new off-shoot in Jutland in the north of the country where a farmhouse and former agricultural buildings has been transformed into a museum. The project was bankrolled by the A.P. Møller and Chastine Mc-Kinney Møller Foundation which uses the shipping dynasty's vast wealth for philanthropy.

3 - Hong Kong police arrested a 40-year-old Irish man and a 32-year-old Filipino woman for the attempted theft of an artwork by French street artist Invader. The Pac-Man mosaic, valued at around $50,000, has been recovered by police after being reported missing from its shopping center site last month by staff.
