Even the extremely popular Cow Parade has been a topic of controversy in a few areas. Since 1999, fiberglass cows have been installed temporarily in over 50 cities worldwide. The cows are decorated in different ways-painted with bright colors, dressed in ethnic clothing, or covered with mirrors or flowers by local artists-and then auctioned off to raise money for charity. But some residents have questioned whether the cows are really art; they think the animals look cheap or are not in good taste, and some have objected to the decoration of particular cows.
