Maurits Cornelis Escher (1898-1972) was a Dutch graphic artist who made illustrations for books, designed tapestries, murals and postage stamps.
He was most famous for making impossible constructions in art, like never ending staircases (that concept was later used in the end of the movie Labyrinth with David Bowie). When he lived in Italy he also made more realistic images.
His works include woodcuts, lithographs, wood engravings, drawings and sketches.
