The Extraordinary Anti-Nazi Photomontages of John Heartfield

From Quazen.com:

In the 1930s the Nazis were gaining ground in Europe. Many chose to ignore or had a laissez faire attitude to the National Socialist policy of expansionism, known as Lebensraum or the threat of war that Germany now posed to the world. John Heartfield (above center, in 1960), a German citizen, was one who chose to criticize the regime through art and he produced a remarkable series of photomongages, the audacity of which still has the capacity to astonishe today.
