The Standing Committee of the Arab Post, at its meeting held in the Omani capital, Muscat, in March 2018, approved the issue of a unified postage stamp, entitled “Jerusalem, capital of the State of Palestine” in all Arab countries, by a unanimous vote of the member states at the request of the state of Palestine.
The commemorative stamp is distinguished by its splendor and importance, as it highlights the features of Al-Aqsa Mosque and the Dome of the Rock. The design also includes the flag of Palestine and two white doves symbolizing peace.
