M.C. Escher (1898-1972) made 448 lithographs, woodcuts and wood engravings and over 2,000 drawings and sketches during his lifetime. He is most famous for his wonderful, so-called impossible constructions and optical illusions, such as Climbing and Descending, which depicts rows of people perpetually scending and descending a flight of stairs. Over 150 prints are on show housed in the former Winter Palace of Queen Mother Emma of the Netherlands in the centre of The Hague. Also for the first time, a huge selection of photos are being exhibited between 4 February and 14 May 2017 at Escher in the Paleis.
