Photographic prints, postcards and some photographic negatives relating to the history of European-Australians involved with the plantation economy of Australian New Guinea. The series include images of Anne McCosker's family and their expatriate associates, local people participating in ceremonial performances, engaged in plantation labour or posing in portrait or group shots, and views of various locations in New Britain, New Ireland and other northern islands of New Guinea where the McCosker family was based. The majority of the photographs were taken in the 1920s, 1930s and the postwar 1940s, and many are captioned. Some were published in Anne McCosker's book, Masked Eden.
There are approximately 1243 b&w photographs, 53 b&w photo postcards and 12 negatives in this series.
