What secrets lie hidden in centuries-old drawings? How can we make these silent masterpieces speak? And how can we distinguish between originals and copies? These and other exciting questions will be answered in Cologne from 14 November 2025 in the exhibition ‘Expedition Drawing – Dutch Masters under the Magnifying Glass’.
