These four stamps from Pakistan, Lebanon, and Egypt were issued to commemorate and advertise the World Health Day in 1978 when the theme was “Down with high blood pressure”. The different countries shared the design of a downwards arrow and styalised heart. The two stamps from Pakistan illustrate one of the important principles when using postage stamps to advertise public health campaigns. The lower value stamp for local postage (20 paisa) has the health message in Urdu. The 2 rupee stamp for higher postal rates such as international postage has the same health message in English allowing both national and international awareness.
