A master of optical illusions, Maurits Cornelis Escher (better known as M.C. Escher) is known to this day for his prints which force you to look twice. For the 120th anniversary of his birth, the Ueno Royal Museum is pulling out the stops with this exhibition full of items on loan from The Israel Museum. That includes some of Escher's greatest hits, such as the four-metre long Metamorphosis II. But that's not all: the exhibition is divided into eight parts, each focusing on a different theme in his works. Enough to spend a lazy afternoon browsing, we'd say.
