Amazon.com description: Product Description: In total 'The Souls' is made up of 4 butterflies, in 80 different colourways, each one in an edition of 15. Vibrant with hue, the finished effect of each image is that of a resonant tension between the stillness of death and the trembling, iridescent life that the individual butterflies convey. 'The Souls' is therefore quintessentially Hirstian, combining the impact of visual spectacle with a powerfully eloquent confluence of medium and visual language. Each butterfly is depicted here and 4 foil block inserts depict the actual foiling used in the prints that the images represent.
