This signature is believed to be ineligible for copyright and therefore in the public domain because it falls below the required level of originality for copyright protection both in the United States and in the source country (if different). In this case, the source country (e.g. the country of nationality of the signatory) is believed to be Azerbaijan.
Note that this tag cannot be used on all signatures, as not all signatures are copyright-free.
This image contains an artist signature that does not constitute a watermark, and should thus not be removed. In some cases it may be useful to provide a version of the file with such details cropped out or otherwise removed, but this should be uploaded as a separate file. For details see: what is not a watermark.
