U.S. Special Delivery (postal service)

U.S. Special Delivery was a postal service paid for with additional postage for urgent letters and postal packets which are delivered in less time than by standard or first class mail service. Its meaning is different and separate from express mail delivery service. Essentially it meant that a postal packet was delivered from a post office to the addressee immediately once it arrived at the post office responsible for delivering it, rather than waiting for the next regular delivery to the addressee. rdf:langString
