On Monday I got not only three postcards but also a cover from Germany.
Opening of the Elbphilharmonie (issued 02-01-2017)
Inside were two German postcards.
The first one shows the Melanchthonhaus in Bretten. The Melanchthonhaus is a museum about the Protestant Reformation and Philipp Melanchthon. It was built between 1897 and 1903 on the site of Melanchthon's birthplace.
The second one shows Peter and Paul Festival in Bretten. The Peter and Paul Festival is a festival about important events in Bretten's history. It is celebrated with many historical costumes and is held every year on the weekend following the Church Day of Saint Peter and Saint Paul. Since 2014 it is a part of the German Nationwide Inventory of Intangible Cultural Heritage.
Thank You very much Charlotte!
