WASHINGTON, DC — Two stamp experts are authors of "100 Greatest American Postage Stamps."

Discussing everything the most distinctive stamp the U.S. ever issued (the $1.00 "Cattle in Western Storm" stamp of the 1898 Trans-Mississippi Issue) to the contest won by a teenager to select the design for the 1938 Presidential Series, Donald Sundman and Janet Klug unveiled their new book, "The 100 Greatest American Postage Stamps," at a special seminar at the National Postal Museum in Washington, D.C.

The event, which drew a packed house on the Museum's ground floor, included a special autograph session following the lecture. Sundman, president of Mystic Stamp Company, and Klug, former president of the American Philatelic Society, offered the crowd a full color PowerPoint presentation to show off their entire selection of the greatest U.S. stamps in history.

The book is published by Whitman Publishing Co., at $29.95 and may be ordered from their website.
