A 22-cent commemorative stamp honoring the bicentennial of diplomatic relations between the United States and the Kingdom of Morocco was issued on July 17, 1987, in Washington, DC. On the same day in Rabat, the Moroccan postal administration issued a 1-dirham stamp with a similar design.
Both stamps recognize the Treaty of Peace and Friendship, the first comprehensive diplomatic agreement between the United States and an Arab, Muslim, or African state. Known also as the Treaty of Marrakesh, the accord endures as the longest continuing friendship treaty between the United States and any nation. It was signed in 1786.
Collectors were able to obtain both the US and Moroccan stamps and first-day cancellations. Designed by Howard Paine, the stamps were produced in the offset/intaglio process by the Bureau of Engraving and Printing in panes of fifty.
