FOREVER. h/t BARE NAKED ISLAM.
The U.S. Postal Service issued its first Eid stamp, with gold calligraphy against a blue background, on September 1, 2001. A new Eid stamp with gold calligraphy against a reddish background debuted on August 12, 2011. All Eid stamps to date have featured the work of world-renowned calligrapher Mohamed Zakariya. The art director for this stamp was Phil Jordan.
Like other stamps in the Holiday Celebrations series, the Eid stamp is being issued as a Forever® stamp. Forever stamps are always equal in value to the current First-Class Mail® one-ounce rate.
The USPS loses billions of dollars annually but they always have money for Muslim stamps. For 1% of the U.S. population.
