Image of photographic experimentation incorporating the reproduction of the same image Untitled black and white image of photographic experimentation by Dye. Each corner of the photograph features a small circle resembling a drawing pin. Each circle is labelled with one of the following descriptions: 'photograph', a 'photograph of a photograph', or a 'photograph of a photograph of a photograph'. The original 'photograph' could be a photograph of a drawing pin, but the poor quality of the image makes a definitive identification difficult. c.1970
