I'm gonna write about Banksy, is a pseudonymous of an England artist who used subversive epigrams combine irreverent dark humour with graffiti.   

The artistic works of political and social commentary have been featured on streets, walls, and bridges of cities throughout the world.

Banksy’s work born in Bristol, in the streets because him use the different walls to account for their social criticism. The government ticks the graffiti as vandalism, but this artist displays his art on public surfaces. 

I like Banksy because him art is very ironic and politic.

In the year 2009 Banksy did exhibition in the Museum of Bristol very interesting.
