I've exhibited with other illustrators on several occasions such as - Picture This: Picture Book Art at the Millenium at the Fitzwilliam Museum in 2000 and at Drawn Here: Children's Book Illustration from Sketch to Finished Page in Ipswich in 2008. Anthony Browne did the posters for both these exhibitions where artwork was not up for sale.
From 1 April - 3 May 2010 I'll be having an exhibition at Newby Hall, North Yorkshire. This is my first one-woman-show and I'll be selling artwork, for the first time, from books like Selkie, Tom Finger and Bruna.
In August another illustrator, Catherine Rayner, will also be exhibiting at Newby Hall.
