Robert Mills will show you the changing faces of Sydney throughout the years from his vast collection of postcards. 100 years ago the postcard was a prime means of communicating with friends and business associates. Multiple mail deliveries per day ensured that messages sent in the am would be delivered in the pm (same day). Cards were also often produced for business use and advertised all manner of activities and products. Maps also appeared on cards. Often the only communication with family members from home the cards that remain tell history as it happened on this, the other side of the world.
