The heyday of the holiday cruise is illustrated in this exhibition of photographs from the museum's archives. Beginning with a black-and-white image taken just after WWI, the show details the changing face of cruising from the strict class delineations of early experiences on board to the 'fun for all' ethos of the 1960s and 1970s.
