The 'Salvator Mundi,' one of fewer than 20 surviving paintings produced by Leonardo da Vinci was seen on display at a Christie's property in Hong Kong on Friday, ahead of its auction at Christie’s in New York. Leonardo da Vinci's 'Salvator Mundi' ('Saviour of the World') is expected to challenge for the title of the most expensive work of art in history. The portrait of Jesus Christ is expected to fetch up to $100 million.
