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 by PM Press in 2009 in the USA) was his first properly published work (although a friend told him that was just vanity publishing anyway - lol), and it became a DIY favourite all over the world.Up to 12% of the author's royalties from the USA editions are donated to charity (BLT Vol.1 was in aid of The Big Issue Foundation - UK registered charity No. 1049077)Don't expect pseudo-intellectual ramblings on what this graffiti all means, how the Banksy phenomenon has taken off, who he is, who he isn't, why my grandmother looks a bit like Arsene Wenger, or what the difference is between graffiti and street art. He's not that interested in intellectualising all this and would rather let you decide what it means to you.Hand printed, limited editions of his black & white photos of graffiti are sometimes available via shellshockphotos.co.uk
