Spear Thrower, Woomera, childs toy, club or Tjurunga? W 05

DescriptionA few questions surround this early stone carved hardwood  piece. What was it used for? The shape suggests a Woomera but It’s too small and un finished suggesting possibly a childs plaything. The carvings are very early and crudely stone carved as some Central Desert items are.Code W 05550mm x 80mm
