English: Signatures on the Joint Comprehensive Plan of Action (JCPOA) document On the top left side, there is a Persian handwriting by Mohammad Javad Zarif, which reads:
مخلص عباسآقا و مجيدآقا
. Translation: [I am] Sincere to Mr. Abbas [Araqchi] and Mr. Majid [Takht-Ravanchi].
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 Iran.
Note that this tag cannot be used on all signatures, as not all signatures are copyright-free.
