Critic Jerry Saltz explains "Why the World's Most Expensive Painting Has Gone Missing" in a Vice video here.  While we're assuming "missing" equates to "out of public view," Saltz claims the reason is that the $450 million Leonardo da Vinci titled "Salvator Mundi" is a "made up piece of junk,"and that "many" think it should be attributed to the "studio of Leonardo da Vinci." 

Utilizing an entertaining old-school slideshow, with a wooden pointer for emphasis, Saltz states his case for why this da Vinci is "not great art," but a "wishlist for money and fame."

The portrait of Christ is still not on display at the Louvre Abu Dhabi since a Saudi prince won it for the institution at Christie's over a year ago, adding even more intrigue to the painting's history of ownership.
