'I commissioned various sign painters to produce enlarged copies of my smaller original images. Once they had completed several versions, I produced a new ‘model,’ compiling the most significant elements of each sign painter’s interpretation. This second ‘original’ was in turn used as a model for a new generation of copies by sign painters, and so on, ad infinitum” … ‘by now it doesn’t matter whether you are looking at a model, a copy, or a copy of a copy.' —Francis Alÿs
