Even experts say that Leonardo da Vinci may have drawn many copies and different versions of Mona Lisa.
Deldicque, the curator at the museum, said the painting had the closest connection to the Mona Lisa. The arrangement of the naked woman's face, hands and body in the picture is almost identical to the Mona Lis.
This sketch and the Mona Lisa are about the same size. The small holes that appear around the woman in the painting show that the drawing could be used as a frame for the oil painting.
According to Bruno Mottin, conservation expert at the Lourdes Museum, the painting was born in the 15th century, when Leonardo was alive and this was not a copy of a lost work.
This picture is difficult to study because it is very perishable. Experts need a lot of time to research before officially recognizing the picture is the work of Leonardo da Vinci. Currently, they are trying to identify the picture that was drawn before or after the Mona Lisa painting was born.
Experts hope that the identity of the painting artist will be completed within two years to prepare for the Leonardo da Vinci's 500th anniversary exhibition at Chantilly.
