This work is an integral part of the series The Nameless Horse. In this case, it has been done on paper with the cyanotype technique, previously making the drawing on an acetate, the positive. Cyanotype is a monochrome photographic procedure, which achieves a negative copy of the original in a blue color, called a cyanotype (blueprint, in English). For its stamping, ultraviolet light is used and the relief is done with water.
