Dr. Seuss is the most famous children's author in the United States. It is difficult to find a child in America who does not know his fairy tale “The Cat in the Hat.” The fairy tale has gone through dozens of editions, and every year the demand for it is growing. Dr. Seuss is not only a poet - he is a kind of graphic artist. He illustrates all his children's books himself. His drawings are also “crazy” - every page is crowded with fantastic animals and little animals, which are not found in any zoology. Even cats, elephants and camels, when they appear on his pages, acquire an outlandish, fantastic appearance. And the secret of his art is that you believe in all his unprecedented grotesque animals as if they really exist, there is so much expression and vitality in them.
