TRIER, GERMANY - MAY 05:  Some of the 500, one meter tall statues of German political thinker Karl Marx on display on May 5, 2013 in Trier, Germany. The statues, created by artist Ottmar Hoerl, are part of an exhibition at the Museum Simeonstift Trier commemorating the 130th anniversary of the death of Marx in 1883. Marx, who was born in Trier, is the author of The Communist Manifesto, and his ideas on the relationship between labour, industry and capital created the ideological foundation for socialist and communist movements across the globe.
