Stamping Singapore as a Colony, State, and Republic

Recently, a colleague asked whether there are any stamps that show Singapore as a British Colony, as the self-overning State of Singapore, and as the independent Republic of Singapore.

The answer is Yes, Yes and Yes.

Here are the stamps.

The date is not shown but we know that Singapore gained independence on 9 August 1965. Thus, stamps with ‘First Anniversary’ would have been issued in 1966.

Why are there no stamps of Independence Day, 9 August 1965?
