This struck me as an emotive, novel and stylish approach to street art. The text is a bit crude but they were produced at different times by (I assume) different artists. The script came first.
There's a great London (now worldwide) street artist called Banksy. I'm pretty sure this is his work - though his more popular work is a bit more...controversial :)
Here's a link: //www.banksy.co.uk/
Check out his "outdoor" gallery. It's really amazing :)
Anyway, very very nice capture, and yay for the BBC Photos feature!! I always keep an eye on their site. I think photos from individuals and their world is way better than what's portrayed in mainstream media.
I think it's awesome and I agree with the message as well. Street art is an avenue all it's own and you chose to go down it and capture it with creativity. Way to go.
