By the time the United States entered World War II in December 1941, the British, French, and Russians had already printed and dropped a host of surrender leaflets on the German Army. The leaflets were of different sizes, colors, texts, and even the surrender instructions were different. There was no overall guidance or uniformity.  This changed with the arrival of American troops in the United Kingdom and their strong alliance. For the first time the two allied nations worked together to prepare a standardized safe conduct leaflet that would be exactly the same wherever used.  The final version of the "passierschein" has been called the most effective single leaflet of the war.

These could be used most appropriately in high school classrooms studying history, various wars, and specifically World War II.  The history behind the "passierschein" is interesting and it might intrigue the students to find other surrender leaflets from other wars and different geographical locations.  The comparison and contrasting values would be both interesting and informative.
