(From the USPS website): Eid Greetings Featuring a design that evokes centuries of tradition, this stamp commemorates the two most important festivals—or eids—in the Islamic calendar: Eid al-Fitr and Eid al-Adha.
The gold-colored calligraphy on the Forever stamp was created by world-renowned calligrapher Mohamed Zakaria of Arlington, VA. The script reads Eidukum mumbarak, “May your Eid be bountiful (or blessed)”
As he has with all previous Eid stamps, Zakariya employed traditional methods to instruments to create the design. He used homemade black ink, and his pens were crafted from seasoned reeds from the Near East and Japanese Bamboo from Hawaii. The paper was specially prepared with a coating of starch and three coats of alum and egg-white varnish, then burnished with an agate stone and aged for more than a year. The black-and-white designed was then colorized by computer. Ethel Kessler was the art director.
