A new work by British street artist Banksy has appeared in New York, a day after he revealed he was beginning a month-long residency in the city.

The first piece of graffiti art, which depicts two boys holding a spray can and is entitled The Street Is In Play, was spotted on 1 October in Manhattan. By Wednesday, however, it had already been painted over.

The second, sprayed on a garage door in a classic graffiti scrawl, reads "This is my New York accent". The words "I normally write like this" are below in neatly printed text.

The BBC spoke with fans of the artist about the prospect of tracking down - and confirming the authenticity - of a new Banksy work every day for the rest of October.
