This item is a ceremonial bull roarer decorated with deeply incised tribal bands as depicted in the photo below that shows both sides. The bull roarer is used primarily for cermonial purposes by the male members of the tribe. Many tourist grade bull roarers are available on the open market today, but this item is the true ceremonial artifact from the Pitjantjara tribe and made in the late 19th or early 20th Century. Length = 35 cm. Width = 5.3 cm. Weight = 120 gm. This item is in very good conditionIt does have a few minor dings to the edges, especially at the two ends. It is still one of the finest bull roarers we have ever seen.
