Postcards began to be produced in Victoria from 1876. Between 1900 and 1920, picture postcards in Australia became an incredibly popular phenomenon. People could cheaply and easily send messages, without the formality of a letter, and they provided a cheap form of souvenir. Eventually, every event of significance was commemorated in some way with a postcard, and this led to the development of a ‘picture on one side and a message/stamp on the other’ postcard we are familiar with today. They were also a popular form of advertising. This postcard appears to be one in a set of postcards promoting the Black Rock area.Colour postcard with a handtinted photograhic image of the cliffs at Black Rock beach, known as Half Moon Bay.
