Six Marilyn Monroe-style Banksy portraits of Kate Moss will go under the hammer later this month.

The pictures, reminiscent of Andy Warhol's classic image of Monroe, are estimated to fetch up to £150,000 at Bonhams' Urban Art Sale in London.

The prints were produced in a limited edition of 20, in six different coloured formats.

Most were sold individually and this group is one of the few to remain in a complete set, Bonhams said.

Another Banksy work being offered in the sale on February 24 is Nola Pink, a canvas showing a girl with an umbrella being rained upon.

The title is based on an abbreviation of New Orleans, Louisiana, and it was one of a series of works the artist painted in the city to commemorate the third anniversary of Hurricane Katrina.

It is estimated to fetch up to £80,000.

Banksy once confined himself to witty graffiti images which would appear overnight in streets in London and his hometown of Bristol but has now become a mainstream painter collected by celebrities.

Angelina Jolie has reportedly spent £200,000 on his work, while the likes of Brad Pitt, Jude Law and Keanu Reeves have also attended his shows.

The American pop star Christina Aguilera once paid £25,000 for three of Banksy's works on a trip to London, including a pornographic picture of Queen Victoria in a lesbian pose with a prostitute.
