Delhi: Artists use street art to spread social messages
Almost non-existent in Delhi a few years ago, street art is now becoming more and more popular.
A two-month street art festival hosted by the city this year was welcomed by artists, public and even the authorities.
Now more and more street artists in Delhi are using walls and fences to create works of art and spread social messages. But some still feel they don't have total freedom of expression.
