Background: The cachet shown on the above first day cover depicts several emblems or symbols of the Sultanate of Oman:

1.     At the top, the emblem of the Post Office with the post horn and the national emblem (see details here-below).

2.    The three colors of the national flag of Oman: white, green and red. The color white historically represents the imam, the Islamic religious leaders of the country, and also stands for peace and prosperity. Green is the color of Islam and represents the fertility of the country as well as Al Jabal al Akhdar (the Green Mountains) in the north-east of the country. The red base is taken from Oman's previous flag and represents the reigning Al Bu Said dynasty, which has been ruling Oman since the mid-18th century and also symbolizes the difficulties Oman overcame in its search for independence. The national emblem is featured at the canton on the flag of Oman.

3.    The emblem of the Directorate General of Civil Aviation and Meteorology, with the national emblem on a red background and two wings.


A Post Horn is shown on the first day cover. The post horn is a valveless cylindrical brass instrument with a cupped mouthpiece. Usually, the instrument has a circular shape or is rolled up with three turns of the tube, although sometimes it can also be straight. From the earliest days of the mounted post rider, the instrument was used by postal couriers and stagecoaches to signal their arrival and departure, before other types of signalling communications (like radio or telegraph). It was also used to act as a warning for other coaches on the road to clear the way and give them priority or have a fresh horse ready, as mail coaches travelled at high speeds. Hence, post horns are frequently used as iconography to represent postal services. 


The National Emblem of Oman is an insignia consisting of a khanjar (dagger) inside its sheath that is superimposed upon two crossed swords; they symbolize the historic weapons utilized by the people of Oman. The sheath is attached by rings to the belt. Adopted in the 18th century as the badge of the Omani royal family, it subsequently became the national emblem of the Sultanate of Oman.
