Strange no, that we adorn the world with pics of ourselves? Think of the prevalence of us in stock images, in advertising space, on the broad sides of buses, men and women smiling. And all the possible wishes that artists themselves hadn't given up this form so readily and instead deal with it. There is a lot of information embedded in our visages. A real psychotic kaleidoscope, ourselves.
