The German Democratic Republic created pamphlets to promote a socialist and peaceful way of life to those living in Eastern Germany. These pamphlets were dropped in the Federal Territory of East German zones in large "propaganda rockets" and small "metal coconuts", along with "occurrence reports" that documents the times they were sent and 'outside occurrences' to spread their news in an innovative, creative and far reaching way. The "propaganda rockets" allowed for more people to be exposed the information over a large geographic scale.
My book titled Bending Spines: The Propagandas of Nazi Germany and the German Democratic Republic (Michigan State University Press, 2004) provides an analysis of much of the material on the German Propaganda Archive. It can be ordered in the United States through amazon . It is also available in a French translation. A Chinese edition appeared in July 2012 but was almost immediately banned by the Chinese government (but not in Hong Kong). It has since been “unbanned.”
As West Germany was reorganised and gained independence from its occupiers, the German Democratic Republic was established in East Germany in 1949. The creation of the two states solidified the 1945 division of Germany.  On 10 March 1952, (in what would become known as the " Stalin Note ") Stalin put forth a proposal to reunify Germany with a policy of neutrality, with no conditions on economic policies and with guarantees for "the rights of man and basic freedoms, including freedom of speech, press, religious persuasion, political conviction, and assembly" and free activity of democratic parties and organizations.  This was turned down; reunification was not a priority for the leadership of West Germany, and the NATO powers declined the proposal, asserting that Germany should be able to join NATO and that such a negotiation with the Soviet Union would be seen as a capitulation. There have been several debates about whether a real chance for reunification had been missed in 1952.
