CowParade is an international public art exhibit that has been featured in major world cities. Fiberglass sculptures of cows are decorated by local artists, and distributed over the city centre, in public places such as train stations, important avenues, and parks. They often feature artwork and designs specific to local culture, as well as city life and other relevant themes.
After the exhibition in the city, which may last many months, the statues are auctioned off and the proceeds donated to charity.
There are a few variations of shape, but the three most common shapes of cow were created by Pascal Knapp, a Swiss-born sculptor who was commissioned to create the cows specifically for the CowParade series of events. Pascal Knapp owns the copyrights to the standing, lying, and grazing cow shapes used in the CowParade events.
