The painting dates back to the late 15th and early 16th centuries, and although it is not certain, its author may have been Leonardo da Vinci.
It was among the home collection of an aristocrat whose family had owned it for nearly a century. Blaker repurchased the painting and placed it in his home in Isleworth, a suburb of London - hence the painting's name, Mona Lisa of Isleworth.After Blaker's death, the painting entered the collection of Henry F. Pulitzer.
During the World War II, it was taken to the United States, and after the war, returned to Europe. There it ended up in a bank vault for 40 years until it was repurchased in 2008 by a Swiss group of investors who had it analyzed in detail. In 2012, the painting was presented to the public.
