Operation Highjump Antarctic Expedition Commemorating The Navy Expedition 1947 New York
From Joseph Mann personal estate. He was enlisted in the Army of the United States in 1913 at Jeferson Barracks, Missouri (see discharge paper). All my First Day Covers and other commemorating envelopes on my listings came from his estate. Discharge paper not included. Can make a copy per your request.
Not a specialist on stamps or covers. To me looks good to very good condition considering age.
See pictures to evaluate condition for yourself. Estate find. Selling as is as found as seen in the pictures. Can send more pictures per your request.
