In Australia, Aboriginal artists have discussed an "authenticity brand" to ensure consumers are aware of artworks claiming false Aboriginal significance. The movement for such a measure gained momentum after the 1999 conviction of John O'Loughlin for selling paintings that he falsely described as the work of renowned Aboriginal artist, Clifford Possum Tjapaltjarri. In Canada, visual artist Sue Coleman has garnered negative attention for appropriating and amalgamating styles of Indigenous art into her work. Coleman, who has been accused of "copying and selling Indigenous-style artwork" has described herself as a "translator" of Indigenous art forms, which drew further criticism. In his open letter to Coleman, Kwakwak'awakw/Salish Artist Carey Newman stressed the importance of artists being accountable within the Indigenous communities as the antidote to appropriation.
