Beautiful old postcard and a great example of German printing. The postcard has some damages (please see scans of front and back), but Santa's kind face, the hopeful expression of the young boy and the embossed and gilded details make this a little treasure.
Germany led the world in printing in the early 20th century. Their postcards were of exceptional quality and were some of the finest examples of early postcard art. Not dated, but circa 1910.
