This work is accompanied by a certificate of authenticity from Papunya Tula Artists which states: 'The roundels in this painting depict the rockholes at the site of Marrapinti, situated in a creek, west of the Pollock Hills in Western Australia. A group of women of the Nangala and Napangati kinship subsections camped at this site during their travels further east. The name marrapinti means nose-bone and people gathered at this site to make them. These bones which are worn through a hole made in the nose web were originally used by both men and women but are now only inserted by the older generation on ceremonial occasions.'
