THE genius of Banksy’s new intervention in central London is not just the image, but the timing of it.Just see how it subverts the generic public statue: they are static and grounded, where this one steps directly into the abyss. And why? Because the man cannot see, blinded as he is by the stuff of his own ideology, his flag.That draped face carries the surrealistic DNA of Magritte’s iconic image, The Kiss.
