Popular printPopular prints is a term for printed images of generally low artistic quality which were sold cheaply in Europe and later the New World from the 15th to 18th centuries, often with text as well as images. They were some of the earliest examples of mass media. After about 1800, the types and quantity of images greatly increased, but other terms are usually used to categorise them.
M. C. EscherMaurits Cornelis Escher (pronˈmourits_korˈneelis_ˈesj-e-r; 17 June 1898 – 27 March 1972) was a Dutch graphic artist who made mathematically inspired woodcuts, lithographs, and mezzotints. Despite wide popular interest, Escher was for most of his life neglected in the art world, even in his native Netherlands. He was 70 before a retrospective exhibition was held. In the late twentieth century, he became more widely appreciated, and in the twenty-first century he has been celebrated in exhibitions around the world.
