Lindauer Portrait Mystery

The Lindauer painting of Kewene Te Haho with direct descendants, 10 years ago. From left, Clinton Kewene and his son Joshua, 3, Mabel Kewene (the chief is her great, great grandfather), and Albert Kewene at Waikato Museum of Art and History. Caption copied from stuff website.

This portrait of Kewene Te Haho sold at auction for $120,000 in 2001 is being investigated as a fake. 
It was the third most expensive Lindauer portrait sold at auction.
