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 Grayson Perry, Dame Helen Mirren, Philip Pullman, John Knapp-Fisher, Quentin Blake and Westlife.
The 2009 theme was 'Words That Mean Most to You' and the auction completed on 12th November. For information on the 2010 campaign visit us in the summer.
