Thank you for viewing my Mercari listing. This item is an Aboriginal boomerang from Australia, made in 1983. It's an original piece from that time. The manufacturing date is on the back, so I believe it was intended as a souvenir. The size is 50 cm, measured in a straight line. The Aboriginal artwork on the boomerang is quite interesting. Originally, these Aboriginal boomerangs were used for hunting, digging, and as weapons, with the inside sharpened. This has been confirmed through research and investigation in Australia, based on old human bones. If you are interested in or have any interest in this Showa-era Australian Aboriginal boomerang, please consider it.
