This hunting boomerang, or throwstick, was made out of Mulga, a dense hardwood found in the Central Desert of Australia. Both surfaces have a rough hewn adze finish. There is a groove cut around the entire circumference approximately 8 inches from the wide end. This groove may have been cut with a metal tool? Also, both edges are thick so that there is no sharp edge, but the airfoils are fully formed. Both of these features are unusual and that is why I acquired it for my collection. Based on color and construction, it was probably made in the late 19th Century. I acquired this boomerang in 1989 from the Barclay Gallery. This boomerang is in very nice condition. There are no chips or dings other than minor construction marks. A very nice example of a Central Desert throwstick.
