The Pitney Bowes Pushing the Envelope campaign is an annual event where celebrities are invited to design an envelope - all of which are one-off original works of art.
Many celebrated actors, writers, illustrators, artists and entertainers have lent their support, including Kate Winslet, Grayson Perry, Lily Allen, Bruce Forsyth and Damien Hirst.
This year's theme for the art is 'Words That Mean Most to You' . The 2009 auction will take place on eBay in November 2009.
