The painting 'Salvator Mundi' or 'Saviour of the World,' previously thought to have been painted by a pupil of Leonardo da Vinci, is now deemed by a team of international experts to be by the master himself.

This once-lost work reportedly will go on view at the National Gallery in London in November. Afterwards, the consortium of American art dealers who picked up the painting at an estate sale six years ago are expected to put it on the market.

While the restoration of the damaged painting revealed to experts that the work was Leonardo da Vinci's, details have yet to be divulged on how the painting was discovered and what it will be valued at.

ARTnews has suggested that it could fetch as much as $200 million. The previous record price for a painting was $140 million paid for a Jackson Pollock in 2006.
