This is a fantastic Yemen Royalist Registered First Day Cover sent from Camp Mansur, with a "Delayed in Transit/THROUGH ENEMY LINES" mark in red on the front.  It was sent to Bel Air, Maryland on August 25, 1965.  It is a special delivery with First Day of Issue Cancels on the front.

There are three wonderful stamps on this amazing cover.  They are SG R46, R47, and R48.

This right here is an absolutely stunning and rare Yemen registered cover, and a must have for any collection.
