In 2010 the United Nations declared 18 July as ‘Mandela day’ (or: Nelson Mandela International Day), an annual international day in honour of Nelson Mandela. Mandela Day (which is also Madiba’s birthday) is a global call to action that celebrates the idea that each individual has the power to transform the world, the ability to make an impact. Mandela’s hand prints included in his ‘My Robben Island’ art project has been adopted since then as an icon-symbol refering to Mandela Day.

Earlier this week South-Africa president Zuma has called for July 18 2013 to become the ‘biggest Mandela Day ever’!
