First World War. A humble brass German military souvenir ring 1914-19

The simple brass ring [approximately 18mm diameter] depicts on the bezel the head of an Imperial German soldier wearing a stahlhelm and beneath this image are the dates 1914  1919 either side of a stylised iron cross. The shoulders of the ring have stylised floral designs. This is the sort of inexpensive little souvenir which would have been produced cheaply in Germany at a time of huge economic distress following its defeat in the recent war. They have probably not survived in any great numbers.
