This photo, taken in 1930 at Circular Quay in Sydney, is part of the Australian National Maritime Museum’s Samuel J. Hood Studio collection. Hood (1872-1953) was a Sydney photographer with a passion for ships.
The museum used the collective power of flickr to discover the identity of the woman in the photo. They now know it is Miss Hera Roberts posing on the deck of the Dutch ship HNLMS JAVA.
