Martin Bull is a photographer, writer and street walker, and wants to share his graffiti / art knowledge with you, rather than keep it a secret.
He's been involved in publications on & off for many years, but 'Banksy Locations & Tours' (self published in 2006 via shellshock publishing in the UK and later by PM Press in 2009 in the USA) was his first properly published work, and it became a DIY favourite all over the world, including a Korean version.
Martin has now had three books about Banksy's street work published in the US & Canada via PM Press, a brilliant radical & independent publisher.
Don't expect pseudo-intellectual ramblings on what this graffiti all means, how the Banksy phenomenon has taken off, who he is, or who he isn't He's not that interested in intellectualising all this and would rather let you decide what it means to you.
He also edits / writes / publishes books about Bristol Rovers (a very unsuccessful English football team) but the audience for them is not quite big enough for the USA :-)
