At first glance he appears to be inches from disaster.

Inches from death... or really? Pavement artist stands on the edge of his drawing of a New York scene - in London

The astonishing optical illusion means he appears to be about to fall from a London rooftop, surrounded by a panorama which includes the City.

But sharp-eyed observers will spot that the street scene below him includes a New York yellow taxi and a U.S. police SWAT team.
 
Pavement artist Joe Hill was commissioned to draw the scene to celebrate the release of Hollywood film Man On A Ledge.

In the film, a New York police psychologist has to attempt to talk down a former policeman who has threatened to jump to his death from a Manhattan hotel rooftop.
