The National Postal Museum and the American Philatelic Society will host the launch of “Stamp of the Century,” a book about the famous philatelic error, the Inverted Jenny. This will be the first readable, popular study of this iconic postage stamp to appear in nearly 30 years. The authors, Kellen Diamanti and Deborah Fisher, will be on hand from noon to 2 p.m. to talk with museum visitors and sign copies of their book, which will be for sale in the museum gift store. (The authors will also be part of the museum’s “History After Hours” program May 2, 6-8 p.m., for an evening book talk and signing.)
Visitors can also view the new exhibition “Postmen of the Skies” which opens on May 1 and celebrates 100 years of airmail service.
