When photographer Duncan Cameron took this picture following a Cabinet shuffle in April 1967, little did he know that he was capturing on film not only the existing Prime Minister but also three of his successors. Cameron was known throughout Canada during the 1950s and 1960s as chief photographer for Time Canada and The Canadian Press. The Cameron collection includes more than 175,000 photographs, negatives and slides, and it records many events that shaped Canadian history of that time. Reproduction PA-117107 |
