Djenne is a village in Mali near the site of Timbuktu. An original Djenne terracotta would be 400 to 600 years old. They are extremely valuable. A figure of a ram, having been verified by several experts and tested, sold at auction for $275,000. It was a fake or actually part fake. The rear part was original. The rest was forged.
