This etching represents two pregnant Eringer cows, a Swiss breed that represents 5% of all Swiss cows, in the fighting mode, which is natural to them. The first image shows how the scratched copper plate looks like once the image is transformed onto the copper plate. Then the plate is placed into iron 3 oxide to, where the acid eats into the copper plate. Then the plate is cleaned and printed, shown on the second picture. By adding the aquatint to the plate makes it look a little darker, shown on the third picture.
