In the beginning was the word? Well, not quite. There’s a cave on the Indonesian island of Sulawesi which contains a painting of three little pigs painted on limestone that is at least 45,000 years old. That significantly predates the oldest recorded examples of writing which only go back 5000 years. In the millennia since words and pictures have gone together, in everything from medieval manuscripts to modern-day children’s picture books. The work of illustrators can be found everywhere from advertising to newspaper editorials, from packaging to, on occasion, the Google logo.
