This exhibition highlights the variety of flowering plants commemorated on US postage stamps during the past 50 years and explores artistic themes that emerged during this period.

My Fellow Soldiers: Letters from World War I

April 6, 2017 – November 29, 2018
Through personal correspondence written on the frontlines and home front, this centennial exhibition uncovers the history of America’s involvement in World War I. The compelling selection of letters illuminates emotions and thoughts engendered by the war that brought America onto the world stage; raised complex questions about gender, race and ethnic relations; and ushered in the modern era. Included are previously unpublished letters by General John Pershing, the general who led the American Expeditionary Forces and a person who understood the power of the medium. In his postwar letter that begins “My fellow soldiers,” he recognized each individual under his command for bravery and service. My Fellow Soldiers: Letters from World War I was created by the Smithsonian’s National Postal Museum in collaboration with the Center for American War Letters at Chapman University.

Please note, this exhibit will be temporarily closed on the following dates: February 5-6, 2018, and July 2-3, 2018.

Featuring original postage stamp art from the United States Postal Service and artifacts loaned by the National Park Service, the exhibition explores the myriad – and sometimes surprising – ways that mail moves to, through and from our national parks.
