Bonhams have just announced their third Urban Art sale, to be held on 24 February 2009. The sale will include an exciting mix of established artists like Banksy as well as emerging names, both British and international.

Six Kate Moss prints by Banksy estimated to make £100,000 to £150,000 at this Urban Art Sale is one of the top items featured. The six Kate Moss prints by Banksy, after Warhol's famous image of Marilyn Monroe, were produced in a limited edition of twenty, in six different coloured formats. As most were sold individually, this group, one of the few to remain intact as a complete set, is particularly collectable.

Another iconic image by Banksy offered in the sale is 'Nola Pink', a unique canvas, depicting a girl being rained upon from beneath her umbrella. It's title is derived from an abbreviation of New Orleans, Louisiana, and it was one of the series of works that the artist painted in the city to commemorate the third anniversary of Hurricane Katrina.

Banksy is quoted as commenting "Three years after Katrina I wanted to make a statement about the state of the clean up operation." It is rumoured that the works were also created as a direct response to the anti-graffiti campaigner, the 'Gray Ghost', who has been active in the city for the last ten years painting over street art with grey primer.

Also featured in this auction is a unique group of eleven works to be sold on behalf of the Prostate Cancer Charity. With the title of Artists11, this project aims to raise both awareness and funds for Britain's biggest charity working in this area, and includes pieces by an eclectic group of artists including D*Face, Dan Baldwin, Andrew Mcattee, Pure Evil, Nick Walker and Blek le Rat.
