American Marconi Wireless News - UK's street artist Banksy unveils latest mural in London

The black and white mural painted on the side of an old building in Bayswater shows two people, probably children, in winter hats and wellington boots lying down, looking up and pointing to the sky.

Banksy, whose real identity has not been revealed, posted an image of the work on his official Instagram account on Monday.

A wide angle photo of the artwork at Queen's Mews, in Bayswater, made it look as if the people in the image are lying on top of a corrugated-iron roof garage, part way up a two-storey building.

In the photo on Banksy's Instagram post, there is an overflowing skip in an alleyway next to the garage, spilling its rubbish onto the pavement.

Above the building towers a crane, with a red light visible at night at the top -- perhaps an allusion to a Christmas tree.

An almost identical artwork also appeared a few miles away under the multi-storey Centre Point building in Tottenham Court Road, where the two children can be seen looking up at the London skyscraper.

Both images attracted interest from passers-by and generated much speculation on social media throughout Monday about whether Banksy was behind them.

But by 4:00 pm only the Queens Mews artwork had been posted on Banksy's social media.

In September, the artist took aim at the UK's crackdown on protesters with a new work outside the Royal Courts of Justice in London, adding fuel to a free-speech row roiling the country.

The artist posted an image of the work, which features a judge wielding a gavel over a protester on the ground holding a blood-splattered placard, on his Instagram page.

The work was later covered by black plastic sheets and two metal barriers.

It appeared after hundreds of people were arrested at a demonstration against a ban on the activist group Palestine Action.

In May this year, one of his paintings, which reimagines Jack Vettriano's famous "The Singing Butler", sold for nearly 4.3 million pounds ($5.5 million) at an auction in London, auction house Sotheby's said.
