Trigger designed the catalogue for an exhibition of Yinjaa Baarni artists' work exhibited at Chalkhorse Gallery in Sydney. This art collective is from the Ngarluma/Yinjaa Baarni communities in the Pilbara, Western Australia. One of the aims of the catalogue was to contextualise these Aboriginal works within the contemporary framework of the gallery, as this was the first exhibition of Aboriginal works that the gallery has shown. The exhibition, in July 2009, was a major success, with all works being sold on the opening night. Further exhibitions are planned for the coming years. The large-scale catalogue has become a collector's item.
