The charity shop painting that Banksy added a Nazi officer to, before returning it to the store it was purchased from, has raised thousands in an online auction.
The work, originally bought for just $50, sold for $615,000 in aid of Housing Works - a HIV/AIDS charity in New York's Gramercy Park.
The piece was purchased by an unidentified buyer at the charity's shop, before being returned by a mystery woman on Tuesday (October 29).
"She said the painting is worth a lot of money and that someone will contact us about it," Housing Works' spokesperson Rebecca Edmondson told Bloomberg.
The store was then called by a member of Banksy's team, who confirmed the work as genuine and explained that Banksy wished them to auction it.
The painting, entitled The Banality of the Banality of Evil, is a classic landscape of a snow-topped mountain and river, to which the artist has added a contemplative Nazi officer.
It takes its title from Eichmann in Jerusalem: A Report on the Banality of Evil, a book by Hannah Arendt, who covered Holocaust organiser Adolf Eichmann's trial for the New Yorker.
The move comes at the end of Banksy's month-long residency in New York, titled Better Out Than In. The artist has caused a stir in the city with a number of highly-publicised exhibitions and installations, including offering his $30,000 artworks for just $60.
However, the final day of the residency was marred by the arrest of two men, who had attempted to steal Banksy's parting gift to New York - a graffiti-style balloon of his name.
