Photo by 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 Ãbergangsrecht. Please use this template only if the author never claimed authorship or their authorship never became public in any other way. 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. For a work made available to the public in the United Kingdom, please use Template:PD-UK-unknown instead. via Wikimedia Commons (Public domain)
