I found this while I was cleaning out my great grandmothers house. I can't really make out what the words say. I know one says Hauptshule. I can't tell what the other word is. Her husband fought in WW2 so I'm assuming it is his. If anyone knows what it is or how much it is worth I'd appreciate it.unnamed[1].jpg20140927_193316.jpgunnamed[1].jpg20140927_193316.jpg
