Judith Noorman lectures about master forgers. She addresses questions such as "What is real?” “How can master forgers often get away with their crimes for so long, and what does that say about our trust?”, “How do you actually produce a fake Dutch master?” And above all, how do you recognise one? In this lecture, current issues, such as the newly discovered Rembrandt paintings and the most expensive painting ever sold: Salvator Mundi by Leonardo da Vinci, are addressed.
