The Sayer Family of Richmond

The attribution of The Sayer Family of Richmond, a family portrait that once belonged to William Randolph Hearst, has been disputed for decades. Recent research has confirmed that it was painted in 1781 by Johan Zoffany, a favored painter of King George III. This new information has the art world abuzz and should help it fetch a hefty sum. In 2011, it sold for £43,000; now the gallery Colnaghi has it priced at £2.75 million. The painting depicts Robert Sayer, a wealthy map publisher, his second wife Alice Longfield, and Sayer’s son James. Their elegant mansion in the background was demolished in 1970, but a new book, Johan Zoffany R.A. and the Sayer Family of Richmond: A Masterpiece of Conversation, written by art historian Dr. David Wilson, has revealed that it was at one time a residence of King William IV. Wilson will give a talk about the painting on July 5th. To reserve a seat contact; 15 Old Bond St.; 44-207/491-8851;
