World War II Patriotic cover
"Let's Go! U.S.A. ... Stamp 'Em Out!"
Uncle Sam stamps on the three-headed snake — the leaders of the Axis powers — Tojo, Mussolini and Hitler. A three-cent United States Scott 905 is affixed to this cover postmarked Waukon, Iowa, October 11, 1943. The cachet is by Artcraft (Washington Stamp Exchange) of Newark, New Jersey.
