To mark the 1100th
anniversary of the Moravian empire in 1963 Czechoslovakia issued this
stamp with a map of the Great Moravian Empire.
Several of the towns indicated on the map,
notably Znojmo (on the far left of the map), are located inaccurately.
I have no more specific information as to the correct location of
Znojmo, or the identity of other towns incorrectly located.
