In the early 1990s, Banksy started working as a freehand graffiti artist and his work became popular in Bristol and London. It is amazing to know that his work features stencils with humorous images; the work also involves slogans.
Most of the messages in his work are anti-establishment, anti-capitalist and anti-war. And more often than not, you will find some subjects like soldiers, policemen, apes, rats and the elderly in his artwork. There are people who have converted some of his prints into cool wallpapers. There was a time when his work would remain in galleries unsold and at other times sell for few dollars. But the following list shows some of the most expensive Banksy artwork of al time.
