there are two types of hunt for white rhino:
darting the animal, which runs i believe around $20,00-30,000.
killing the rhino as in a regular hunt, and for this one i would imagine $70,000 and up for the hunt. there are several countries where white rhino are on quota with available cites permits--south africa, zimbabwe and namibia i think. this one is likely on a ranch where it can be protected fom poaching and it is likely they know just where it is at all times so the hunt might not be that challenging. i think the label is actually placed on the pictures and no on the animal to prevent unauthorized usage. however, when i went nilgai hunting, there was a huge pig that had "do not shoot" painted on him as he was a pet and hung around the headquarters.
