In the Foreword, Quentin Blake discusses Dickens' story, saying, "At the centre is the wonderfully drawable, memorable figure of Scrooge. He seems the very spirit of anti-Christmas...But he is human all the same, and in the travels of that strange Christmas Eve he finds his true human feelings again. In his company we are reminded (as we still need reminding) of the importance of generosity of spirit, and the possibilities of worth in ordinary people."
Quentin Blake is a well-known and beloved illustrator in both his native England and in the US. Blake's characteristic quirky pen-and-ink and watercolor sketches are an excellent complement to Dickens' story. Full page and spot illustrations, some black and white and others in full color, are scattered throughout the book. Blake is probably best known in the United States for his illustrations of children's books by Roald Dahl, including Charlie and the Chocolate Factory and James and the Giant Peach. Blake's artwork is so distinctive that once you see his artwork, you will recognize other examples of it immediately from then on.
