Bowdlerisation for the 21st Century
by Samuel Jones
In his video for It's a Material World, Tom looked at street art and interviewed one artist who raised the question of what kind of heritage and legacy was being lost when images are painted out or cleaned up.
Last week, the Street Art Awards were held. The public could nominate works for consideration, and then an open party was held in which the winners were chosen.
The third placed image - by Banksy - speaks to some of the discussion in the video.
