The 11th of November marks Veterans Day in the US and Armistice Day (or Remembrance Day) in many Commonwealth countries. It marks the end of the First World War in 1918, but has since grown into a day to remember all those who have fought and fallen in the wars that have come and gone. And those who are still fighing in wars such as in Iraq or Afghanistan. In the almost 100 years since the end of the First World War a lot has changed. Better and deadlier weapons, better communications and better medical aid, but one thing has not changed. Fighting a war is as much about firing your weapons as it is about winning the war of the mind. It was like that in the muddy trenches of Flanders and it is still like that in the dust of Afghanistan. One such battle of the mind is fought through the use of graffiti.
