On Thursday I got not only a postcard but also a cover from Germany.
500 years Reformation (issued 13-04-2017)
It is a joint issue with Brazil.
with a special postmark showing the Veste Coburg
The Veste Coburg is a castle in Coburg. It is one of the largest castles in Germany and was never conquered. In 1530 Martin Luther lived in the castle for a few months.
