Advertising using post marks applied through machine cancellations was also part of the general overall strategy developed by Harry Brown. He saw post marks as yet another avenue through with the public could be made aware of the uses of telegrams.
Ten slogans were used over the period 1932 to 1974. They covered a variety of themes ranging from recommending general use of telegrams to using specific types of telegrams and services.
The general details of each slogan are provided below. Details of the types and formats of all the slogans analysed in the Census of just on 1500 slogans from 48 Post Offices throughout Australia at which one or more slogans were used can be accessed elsewhere.
The nature of the machines required the slogans to be 20 mm high. Details coming.
