The Fondation Custodia holds one of the finest collections of prints put together by a private collector in the twentieth century. Very critical about what he bought, Frits Lugt was always on the lookout for exceptional impressions. The collection reflects Lugt’s taste and has a number of core sections, among them portrait prints, including highlights of the French engraved portrait art by Robert Nanteuil (1623-1678) and the set of portraits that form the Iconography by Anthony van Dyck (1599-1641).
