In order to promote deeper understanding and awareness of the goals and objectives of the Economic Cooperation Organization (ECO) amongst the peoples of the Region and abroad, ECO Cultural Institute (ECI) suggested designing a Unified/National stamp for the commemoration of 20 years of Expanded Cooperation in Economic Cooperation Organization (ECO), to be observed on November 28, 2013 (ECO Day), by the interested National Post Offices or other relevant authorities of all ECO Member States, simultaneously. To this purpose, ECO Cultural Institute submitted a draft design to the 12th ECI Council of Permanent Representatives and conveyed it to the ECO Secretariat and ECO Embassies in Tehran for further measures.
