The Michaelis Collection at Cape Town’s Old Town House is renowned for its collection of Dutch and Flemish masters such as Frans Hals, Jan Steen and Anthony van Dyck, and “is seen as one of the best of its kind outside the Netherlands.” Next month the museum is opening a show that will flip these paintings with the faces to the wall. The exhibition “Flip” is “a conceptual art intervention” on one of the country’s premier art collections.
