Researchers have unearthed painting of nude Mona Lisa

Scientists at Louvre in Paris have been examining a charcoal drawing known as Monna Vanna that was kept at a quiet corner of a palace north of France. Curators from the museum believe the drawing is at least in part by Leonardo. The size is same as the original Monalisa painting.

Curator Matthew Deldik was impressed at the line drawings of the sketch and believes none other than Leonardo could have come up with such geometrical precision. The painting is rarest of rare and if proved to be a Da Vinci original, it will surely be an invaluable addition to the art world.
