Banksy poster design under the hammer

A charity poster designed by graffiti artist Banksy could raise as much as £80,000 when it is sold at auction next week.

The original artwork was designed for Greenpeace's Save Or Delete campaign and was intended to highlight the problem of deforestation.

It features characters from Walt Disney's The Jungle Book film put on to an image of a devastated forest but was never used because of copyright issues.

It will go on sale at Bonham's auction house in New Bond Street, central London, on Tuesday January 11.

Also going on sale is a work by graffiti artist Futura 2000, painted on stage during a performance by the Clash on their Combat Rock tour.

It is estimated to sell for between £15,000 and £20,000.

A screen print of a Barack Obama Change poster by American artist Shepard Fairey, supporting his 2008 presidential campaign, is expected to fetch £1,500.
