The photograph shows Keith taking a "whisper ballot" from a voter during the first PNG general election in February 1964. The election patrol of which he was a member walked through mountainous terrain south of Chuave in the Simbu region gathering votes as part of the massive nationwide operation to bring democratic government to the then Australian territory.
