A HIGH-FLYING piece of street art, thought to be by the artist, Banksy, has appeared on the side of a city centre building.

The 15-feet tall spray painting is of a monochrome biplane with a heart-shaped smoke trail.

It has been dubbed the “Love Plane” by Twitter users and can be seen on the side of Norwich House, next to Rumford Street car park, opposite the Liverpool War Museum.

Speculation that the artwork is one of the world-famous artist’s own was further fuelled when photographs appeared on Banksy’s own website.

The piece depicts an intricately stencilled black-and-white biplane with a white smoke trail in a heart shape.

Bankys’s work has fetched hundreds of thousands of pounds at auction in the past. A spokesman for Liverpool council said: “We are not taking any action.

“It’s on private property and there have been no complaints about it.

“We would only normally remove it if we had received complaints about it.”

Although the council has no plans to remove the artwork, the owners of Norwich House may still decide to take action to remove the graffiti.

The piece of street art is almost identical to one that was spotted in Tower Hamlets in London last week, which has since been removed.

The side of the New Tower Buildings, on Wapping High Street, was decorated with a version of the artwork featuring a red heart-shaped loop.

In Liverpool, Banksy is well known for the gun-toting rat which first appeared on the site of the Whitehouse pub, in Chinatown, during the 2004 Liverpool Biennial.
