What is Really Behind Art Market Secrecy?

What really is behind
art market secrecy?

Dealers give many reasons why they are failing to revel the collecting histories of the artefacts they trade in. Most of it is bla-bla, but a case going through the courts involving Russian potash billionaire Dmitry Rybolovlev the former owner of fertilizer business Uralkali sheds some light on the less salubrious among them. Blatant profiteering from a limited supply and boundless greed ('Russian billionaire buys Salvator Mundi, dealer makes $50 million killing' The History Blog April 5th, 2015). The case involves the alleged rediscovery of Leonardo da Vinci’s Salvator Mundi and its sale to Mr Rybolovlev's collection by Swiss businessman Yves Bouvier.
