George the 5th and 6th-Continuity of Designs in British Empire Postage Stamps

Illustrated below are two examples of how designs were re-issued for the reigns of different British monarchs with the same value and design with the monarch's portrait the only difference. The examples are of stamps issued for Kenya, Uganda, Tanganyika but examples of many British colonies illustrate this. Many of the designs for Elizabeth the 2nd issued for British colonies showed the continuity of design. Psychologically important perhaps for the smooth running of imperial policy even in times of succession and change.
