Read the poster from Allen gardens---seems a fair request, yeah? Banksy dabbled with spray cans early in his career, but has long been identified with his stencil mastery. The man is a genius, with his take on witty social comment. I see a straight line going from '60s protest songs to his works. A pair of his originals have recently been uncovered in the Shoreditch/Hoxton area, but seem to have been removed by opportunistic 'investors'.
