This photographic artwork depicting a young boy fills the entire side of a four-storey terrace in Herbrand Street, Bloomsbury - but it has not necessarily impressed those living nearby.
The image, which has been printed on paper and pasted onto the property's side wall, is by a French artist known as "JR", whose work currently features in an exhibition of street art at Tate Modern.
JR told a local newspaper: "It's a mural, it's there for a period of time and can come off very easily. If people don't like it they can criticise it or scratch it off.
"It's not my piece of art any more, it's in the street for everybody."
The image is expected to be removed in the next few days but it has been condemned by the Bloomsbury conservation area advisory committee.
Chairman Bill Reed said: "While many sites can benefit from this sort of thing, a listed building in a conservation area definitely doesn't."
