In 2003 Ralph Hotere painted White Drip II as a protest against broadcaster Paul Holmes for referring to United Nations secretary-general Kofi Annan as a "cheeky darkie" on his radio show. Holmes purchased the painting and now (following his death earlier this year) it is going to auction with an estimate of $140,000 - $170,000.
