The Australian feels that Sotheby’s is moving into new territory:

Sotheby’s Australia has entered the primary art market with the sale of 54 artworks by Albert Tucker, most of which have not previously been offered for sale. Sotheby’s has turned its showroom in Woollahra, in Sydney’s east, over to the paintings, which are owned by the late artist’s estate. Many have been painted on paper and are quite small. Some are recently framed and in pristine condition after being kept in drawers since they were created. Sotheby’s head of art, Geoffrey Smith, said the expansion into the primary art market would put the company’s showroom to good use. The move would also extend the Sotheby’s brand, which in Australia had been confined to the secondary auction market.
