              Note: In Germany and possibly other countries, certain anonymous works published before July 1, 1995 are copyrighted until 70 years after the death of the author. See  Aktuelle Rechtslage in Deutschland, last paragraph. If the author identified her/himself publicly, do not use this template. If the work is anonymous or pseudonymous (e.g., published only under a corporate or organization's name), use this template for images published more than 70 years ago.
