The elusive painter released a video on Sunday night of an elderly man selling what appeared to be knock-off versions of the artist's iconic work.

But they were actually original pieces painted and signed by the anonymous artist, who is currently exhibiting in the city.

A bored-looking old man was in charge of the stall

The video shows just eight of his paintings being sold - four to a man from Chicago, two to a woman for her children and two to a young woman tourist from New Zealand.

The Chicago buyer told the old man he was redecorating his house and just needed something for his walls.

The paintings are estimated to be worth up to €24,000 each.

When the vendor packed up his stall at 6pm, most of the works were still unsold.

Banksy has moved to New York for a month, and as part of a series called Better Out Than In has promised to do a new piece of work every day.

Each piece is posted to the artist's Twitter and Instagram account, and locals then race to find the location of the artwork before it is removed.
