Flag of Guyana

The national ensign of Guyana is a version of the national flag with proportions of 1:2. The civil air ensign is a version of the British Civil Air Ensign with the Guyanese flag in the canton. During its colonial period, Guyana's flag was a Blue Ensign with the colonial badge in the fly. An unofficial red version was used at sea. The first flag was introduced in 1875 and was changed slightly in 1906 and 1955. Like all British Ensigns, the colonial flags of Guyana were all ratio 1:2. ==Presidential Standards==

The Presidential Standard of Guyana came into effect by Proclamation issued on 23 February 1970. Subsequent Presidents have amended this Proclamation to replace the description of the flag contained, to reflect the Presidential Standard they wish to introduce for the duration of their presidency. ==Joint Services==
