This is a very nice set: the 1871 Kriegsdenkmünze medaille together with original 1871 citation (urkunde).
The citations are very hard to find!
The Kriegsdenkmünze für die Feldzüge 1870/71 was a commemorative medal for the French-german war of 1870/1871. The medal is one of the originals, with on the edge written: “Aus Erobertem geschut” (Made of conquered Canons!)
These medals were made as a visual and actual remembrance item to carry by German veterans of the French-german war of 1870. The medals were made of actual conquered and melt down French canons, thus every veteran could Always carry a piece of the former enemy with him.
Toghetr with original citation, a very hard to find set!
