I found this German postcard that is from the turn of the 19th century. If you read German, you may want to enlarge the image to see the bottom. All I could make out is what appears to be child or baby and protector.
There are many German postcards from the Victorian Era, when people were very sentimental and kept baby books, teeth, hair, etc. Many of these are still widely used in scrapbooking.
Germany’s attitudes toward Christianity would later change and further descend through World War I , before the Nazi party came to power in the late 1920’s and 30’s giving way to the destructive regime and eventually World War II.
