This image is in the public domain because it is a mere mechanical scan or photocopy of a public domain original, or – from the available evidence – is so similar to such a scan or photocopy that no copyright protection can be expected to arise. The original itself is in the public domain for the following reason:

Public domainPublic domainfalsefalse

This image (or other media file) is in the public domain because its copyright has expired and its author is anonymous. This applies to the European Union and those countries with a copyright term of 70 years after the work was made available to the public and the author never disclosed their identity. Important: Always mention where the image comes from, as far as possible, and make sure the author never claimed authorship. 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 Übergangsrecht. 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.

This tag is designed for use where there may be a need to assert that any enhancements (eg brightness, contrast, colour-matching, sharpening) are in themselves insufficiently creative to generate a new copyright. It can be used where it is unknown whether any enhancements have been made, as well as when the enhancements are clear but insufficient. For known raw unenhanced scans you can use an appropriate {{PD-old}} tag instead. For usage, see Commons:When to use the PD-scan tag.
