From ArtDaily.org:
LONDON.- Seventeen art works by the celebrated graffiti artist, Banksy, will be available to photograph at Bonhams, New Bond Street, ahead of the Urban Art Sale, which takes place on 29 March 2012. One of the highlights is a screen print of British supermodel Kate Moss, 2005, inspired by Andy Warhol’s iconic Marilyn Monroe series, which has been estimated at £30,000 – 50,000. It will be on display alongside Warhol’s screenprint of a Dollar Sign (estimate £20,000 – 30,000), which is part of the Contemporary Two: Modern Design sale, also on 29 March 2012.
For a fascinating look at Banksy and his work, I highly recommend taking a look at his 2010 documentary, Exit Through the Gift Shop
