This work is accompanied by a certificate of authenticity from Manigrida Arts and Culture which states in part: 'The Lorrkon or bone coffin ceremony was the final ceremony in a sequence of mortuary rituals celebrated the people of Arnhem Land. This ceremony involved the placing of the deceased bones into a hollow log which was decorated with painted clan designs and ceremonially placed into the ground where it remained until it slowly decayed over many years. The log is made from a termite hollowed stringybark tree (Eucalyptus tetradonta) and is decorated with totemic emblems.'
