Images, and the words that oftentimes accompany them, have a tendency to take on lives of their own.  The mustache sported so famously by Hitler represents many things.  It represents fear, violence, extermination, destruction, hate.  The very fact that someone would use an image as loaded as that of Hitler to make a statement about an economic policy is irresponsible.  That being said, the policies born from economic theories have had huge impacts on the lives of millions upon millions of people.  

The movement has risen in popularity and sparked the interest of a broader public. But to those not active in the art scene, the term remains vague. In a first step to improve the understanding of urban art, one needs to look at where it originated: the movement started on the streets of urban environments where works were put up illegally, conveying messages the artists felt were otherwise not being heard by the masses. At this stage--when it can’t be sold or exhibited in a gallery--urban art is considered street art.
