October 15, 1928 – The airship, Graf Zeppelin completes its first trans-Atlantic flight, landing at Lakehurst, New Jersey, United States.
Pictured below is a set of 3 stamps issued in 1930 by the U.S. commemorating the Graf Zeppelin. These are very popular stamps among collectors of U.S. stamps and some philatelists specialize in collecting only Graf Zeppelin stamps in various formats, e.g. on covers with historical significance, with various postmarks and cancellations, plate blocks, mint never-hinged singles and used singles.
In fact, I recently met Cheryl Ganz, Chief Philately Curator of the William H. Gross Stamp Gallery of the Smithsonian National Postal Museum, at the MILCOPEX stamp exhibition in Milwaukee, Wisconsin. Cheryl was signing copies of her new book Every Stamp Tells a Story, and as she was signing my copy, she shared with me that she is an avid collector of Graf Zeppelin stamps.
