10th Anniversary of Malaysia

Malaysia was founded in 1963. These three stamps on the cover displayed were issued to commemorate the 10th Anniversary of the foundation Day, namely on 31 August 1973. 
The cover displays the flag of Malaysia, surroundd by the standards of the 13 States. A little bit about the Federation that is Malaysia may be of interest. Malaysia is a federation of 13 states and three federal territories. These are divided between two regions, with 11 states and two federal territories on Peninsular Malaysia and the other two states and one federal territory in East Malaysia. Governance of the states is divided between the federal and the state governments, and the Federal government has direct administration of the federal territories.The 13 states are  based on historical Malay Kingdoms, and 9 of the 11 peninsular states, known as the Malay states, retain their royal families. The King is elected by and from the nine rulers to serve a five-year term. Each state has a unicameral legislature known as the State Legislative Assembly. The states of East Malaysia (Sabah and Sarawak) have separate immigration policies and controls, and a unique residency status. For citizens of one of these states or Peninsular Malaysia, the other areas of Malaysia are considered foreign countries under immigration laws. 
Each state is further divided into districts, which are then divided into mukim. In Sabah and Sarawak districts are grouped into divisions. The federal parliament is permitted to legislate on issues of land, the Islamic religion and local government, in order to provide for a uniform law among all states. It may also intervene at the request of the state assembly concerned. Except for some land related laws, the state assembly must also pass the in question. Non-Islamic issues that fall under the purview of the state may also be legislated at the federal level for the purpose of conforming to Malaysian treaty obligations. This FDC was given to me by my dear friend Maria.
