A design on the left side of the envelope (a "cachet") explains the event or anniversary being celebrated. Ideally the stamp or stamps affixed relate to the event. Cancels are obtained either from the location (e.g., Cape Canaveral, anytown) or, in the case of the United States, from the Postal Service's Cancellation Services unit in Kansas City. 60 http://www.sporkmonger.com/projects/feedtools/ http://www.stashmatic.com/i/JUN-79444/Dave-Crockett-San-Antonio,-TX-1967-08-17 Thu, 20 Dec 2007 09:16:50 +0000 http://www.stashmatic.com/i/JUN-79444/Dave-Crockett-San-Antonio,-TX-1967-08-17
