Martin taught himself to draw cartoons when the publisher of his first book suggested he illustrate it. He went on to enjoy a long and successful career as a cartoon illustrator, making his living by coming up with ideas for book jackets, magazine articles and more.
Nowadays, Martin still does the occasional specially commissioned cartoon but mostly publishes his cartoons on Twitter. They are popular on social media and he regularly gets inquiries from publishers from around the world who want to license them.
For many years, he and Martha have run versions of their popular Cartoon Thinking workshops for many different organisations. Contact us if you'd like to know more about how to commission one of these workshops.
