In 1918 the nation of Czechoslovakia was
created out of territory which had formerly belonged to the
Austrio-Hungarian empire. The provinces of Bohemia and Moravia were
the center of industry and were the homeland of the Czechs. The
history of the Czechs and the Slovaks as well as their society and
culture differed substantially. There was a large German minority in
the Sudetenland. This became the pretext for the dissolution of
Czechoslovakia after the Munich Conference in 1938.
Four stamps issued in 1939 during the German occupation
of Bohemia and Moravia, declared the nationalist sentiment of the
Czechs. By aligning the stamps properly, the outlines of the vignettes
make up an outline map of the state of Czechoslovakia.
This is an example of what
is known as a "ghost image," and while it is visible to one who is
properly prepared, it is unclear that it was intentional.
