Who has illustrated most of Roald books?

The most prolific illustrator of Roald Dahl's books is Quentin Blake. He has illustrated over 20 of Dahl's books, including some of his most famous works such as:

* Charlie and the Chocolate Factory

* Matilda

* The BFG

* Fantastic Mr. Fox

* James and the Giant Peach

Blake's distinctive style, with its simple lines and expressive characters, is a perfect match for Dahl's witty and imaginative stories. He has become so synonymous with Dahl's work that it's hard to imagine the books without his illustrations.
