The Netherlands and France have signed a treaty over Rembrandt’s twin portraits of Maerten Soolmans and Oopjen Coppit. The pact between Dutch Minister for Education, Culture and Science Jet Bussemaker and her French counterpart, Fleur Pellerin, includes arrangements for the works to be restored in the Netherlands and then exhibited here in their full glory for the first time.
