A painting hanging above a fireplace in a house in London since 1960. This painting is not only drawn by Leonardo da Vinci, but also a previous version of the world-famous portrait. An art collector named Hugh Blaker bought the painting in 1913 from an English nobleman for his archive.

The nobleman himself bought the painting from Italy in 1778. But the painting was hidden from the public until 2008.  In 2015 and 2016, expert studies on the painting began, until researchers claimed that the painting had been painted by Da Vinci himself.
