The article presents a few of the conservation efforts undertaken in order to unwrap and ready Thomas Sully's The Passage of the Delaware for its new place of honor in the new American Wing. The brief video below shows the large-scale efforts to get it in place.
It's an interesting exercise to compare and contrast two artists' interpretation of the same scene in history, as well as the history of the two paintings themselves.
Thomas Sully's "The Passage of the Delaware" 1819
Emanuel Leutze's "Washington Crossing the Delaware" 1851
Leutze's painting (Metropolitan Museum of Art) has become an iconic image of Washington whereas Sully's was never given a proper viewing venue.
