Mystery over Christs orb in $100m Leonardo da Vinci painting
$450 million is a lot of dough for a painting whose authenticity is at all in question.
Considering that the Saudis are usually shrewd investors and this acquisition comes at a time of financial strain for the KSA, not to mention one of upheaval, I would think the purchaser has gone to great extremes to have the painting examined.
Great mystery here.
