Did Leonardo da Vinci draw a nude Mona Lisa?

Could Leonardo da Vinci have drawn a nude version of The Mona Lisa? Art experts say that is entirely possible.

This charcoal drawing, titled the Monna Vanna, is now thought to have at least been partially rendered by the famed artist. A Curator at the Conde Museum in France points out that there are several aspects of the two works that are almost exactly the same.

The drawing is nearly the exact same size as the Mona Lisa and the hands and body are virtually identical. A Louvre Conservation expert, also confirms that the drawing was made during da Vinci’s lifetime. The piece also has small holes around the figure that could have been used for tracing the image onto the canvas.

Though compelling as it is, not all evidence points towards the famed renaissance genius. Some parts of the drawing were done by a right-handed artist and it is known that Leonardo da Vinci drew with his left.

Experts hope to make the attribution official by the time the 500th anniversary of da Vinci's death rolls around in 2019. One thing is for certain though, if this is Mona Lisa, she looks a little more cheerful in the buff.
