I recently took part in 'A Letter in Mind' exhibition at the Oxo tower gallery in London. Artists were invited to create their piece using only a simple white envelope and the title 'A letter in mind' as a starting point. There was a huge variety of responses, and some well known names involved, including Grayson Perry and Chris Haughton. Works were exhibited anonomously and then auctioned off in aid of the National Brain appeal, with the name of the artist only revealed once a purchase had been made. For my piece I used the address of the National Brain appeal which I broke down and fully illustrated on the front - I then sent the piece directly through the mail, hoping it arrived unscathed - luckily it did! You can see the full range of artworks on this link.
