The art of the 20th century has been dominated by two men, Matisse and Picasso. Henri Matisse is regarded as the "Master of Colour" It was at the end of the 1940's, when eighty years old and increasingly infirm, that Matisse embarked on a new style which was to prove to be one of the greatest achievements of his art, the idea of creating images with collages of cut paper painted in strong colours, often combined with single stroke drawings using a broad brush in indian ink, creating truly magnificent posters. The great works of this period have become amongst his most celebrated creations.
