This work first published in the Ottoman Empire is now in the public domain because the Empire's copyright formalities were not met (copyright notice, registration, and deposit), or because the copyright term (30 years after the death of the author, sometimes less) expired before the Empire was dissolved (details).

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 Turkey.
