The allied also used postcards and feldpost for their purposes. You can see examples in this slide and the next.
Here you see the front and back of a postcard with the face of Party member Dr. Walter Scheiber. The title under it is 'This german man is free'.
On the back a description is given of the meaning of the title. It states to the normal German citizen that party members like Scheiber are free from front duties, free from rationing, and so on. All things the 'normal' Germans were suffering from.
Very special of this card is the affixed 'FORGED' stamp. In fact, Delmer and his men made different types of forged stamps of which this is a good example.
These cards were ballooned over Germany. Once one of these balloons did not do its work as it should do. It decended in Holland were several young boys removed cards from underneath. After that they went to get there friends to have a look at the balloon also. They just left as the balloons destruction device exploded ....
