Da Vinci? (please say that like Tom Hanks in the trailer 2006 film  The Da Vinci Code) The last privately owned Leonardo Da Vinci (of Ninja Turtles fame) painting, Salvator Mundi was auctions off last week at Christie’s in New York. it went for….. $450,312,500 making it the most expensive painting ever sold.  Paintings by the old master are rare (less than 20) and finished paintings are ever rarer. While we all hoped the piece would end up in a museums collection, the outrageous price dictates that might not have happened.  As of the writing the buyer is still unknown. IS IT REAL? Who knows.  Seriously, this work has been beaten…
