Events in 1938-1939 Europe were among the worst in modern history. Hitler’s armies marched into Austria and Czechoslovakia in 1938. And by that November, in an act of vicious intimidation known as Kristallnacht, Nazi thugs vandalized Jewish businesses all across Germany. The genocide began as tens of thousands of Jews were sent to concentration camps. During September 1939, Germany invaded Poland, starting the most horrific and bloody war in the history of the world.
America in 1939 declared itself neutral in the European war. At the Post Office Department, eleven commemoratives were issued that had a total printing of over 820 million stamps. Each individual commemorative had total printings averaging over 74 million stamps.
