Lindner Kueps cobalt miniature plate Caroler girl sings

Not sure what these little miniature plates are all about?? Or, how they were issued. This same company made the large size, numbered limited editions, exactly the same.. except they had the title of plate on the front (These mini plates do not). Not sure what the large one of this was named as I could not find one anywhere. A little girl singing Christmas carols on a snowy eve, with a little dog sitting by her.
