A man from the Gaza Strip has told the BBC he was tricked into selling a work painted by UK graffiti artist Banksy.
The image of the Greek goddess Niobe, weeping for her dead offspring, was painted on a door from the ruins of Rabie Darduna's house in Gaza City.
It can be seen in a video released by the secretive artist after his surprise visit to the Palestinian territory a month ago and is on his website.
A local buyer gave Mr Darduna just 700 shekels ($175; £118) for the picture.
However, original Banksy artworks have recently sold for hundreds of thousands of dollars.
The Darduna family property was one of some 18,000 in Gaza that were destroyed during last year's 50-day war with Israel, displacing 110,000 people, according to the United Nations.
"It was a two-storey building but only the door was left standing," says Mr Darduna. "Then a young, foreign man came and painted on it."
The father-of-six says that after the picture began to get media attention he was approached by a group of men.
They convinced him they were acting on behalf of the artist and wanted to buy the door, as it was part of a series of works.
"They said they wanted to put it in a museum in Gaza where everyone could see it," Mr Darduna explains.
"One man told me: 'We're from the group that did it.' They made me sign a paper. It said I agreed on 700 shekels. They pressured me and I accepted because I need the money."
Since losing their house, 20 members of the Darduna family have moved into a cramped, rented apartment, sharing just two bedrooms.
When the BBC contacted the buyer of the Niobe picture he insisted the purchase was legal and refused to comment further.
On Wednesday rumours began to circulate that it had been returned to the family, following media coverage. But the buyer later posted on his Facebook page that the door was still in his possession.
"Really we feel depressed and very upset," Mr Darduna. "This door is rightfully ours. They cheated us. It's a matter of fraud. And we're asking for the door to be returned."
As well as the painting of the goddess, Banksy left murals of a pink-ribboned cat playing with a ball of mangled metal and children swinging from an Israeli watchtower.
On a wall he wrote: "If we wash our hands of the conflict between the powerful and the powerless we side with the powerful - we don't remain neutral."
In a two-minute satirical video, suggesting Gaza as a tourist destination, the artist - whose true identity is not known - sought to highlight the plight of its residents.
Many who have been displaced have begun to lose hope.
They have returned to their damaged homes, patching them up or camping outdoors, while they wait for promised financial support and construction materials so they can rebuild.
More than $5bn (£3.4bn) was pledged in international aid. However the authorities in Gaza say little has arrived.
Banksy has previously visited the occupied West Bank at least twice.
His street artworks in Bethlehem - including some on Israel's separation barrier - are now a tourist attraction.
A Banksy shop sells magnets, T-shirts and other customized souvenirs.
However here too, his murals have stirred up tensions. Those showing a donkey and a rat were initially thought to be insulting and were painted over.
Others were cut down and sold for much less than their true market value. Art dealers shipped at least two overseas.
"At first nobody knew who Banksy was, not even me and I was involved in his exhibition," says artist, Ayed Arafah from Bethlehem's Dheisha refugee camp.
"Artists could see his work had a special character but other people just thought he was like any other international [figure] who came to make graffiti on the wall and support the Palestinian cause."
"But then it became clear how many foreigners came to see the work and slowly people realised what it was worth."
"Now I think that even if [Banksy] drew something very small - even a dot - people might cut down their walls and try to sell it."
