The art cows could be coming to Edinburgh, home to some pretty great art of its own. “There is no question that they [the cows] have been popular, attracting tourists and generating a buzz. So I’m sure you are wondering what grumpy cow would dismiss a herd that brightens up our streets and gives money to good causes. My problem with this exhibit is that it is one of many banal but inoffensive displays littering our public spaces.”
