Experts at the Louvre in Paris have been examining the drawing which has long been attributed to Leonardo da Vinci's studio. /VCG Photo

A curator at the Paris museum believed that the artwork was painted by the Renaissance painter himself. Experts found that the work dated from Leonardo’s lifetime, drawn by a left-handed artist, and moreover, the figure’s hands and body are similar to the Mona Lisa. /VCG Photo

Even though experts cannot "absolutely confirm" the work’s painter, the artwork will be displayed at Conde Museum to mark the 500th anniversary of da Vinci’s death. /VCG Photo
