This is a faithful photographic reproduction of an original two-dimensional work of art. The work of art itself is in the public domain for the following reason:
As such, works published by citizens of Iran in Iran are usually not subject to copyright protection outside of Iran. Hence, such works may be in the public domain in most other countries worldwide.
However
Works published in Iran by citizens or permanent residents of other countries that are signatories to the Berne Convention or any other treaty on copyright will still be protected in their home country and internationally as well as locally by local copyright law.
Similarly, works published outside of Iran within 30 days of publication within Iran will also usually be subject to protection in the foreign country of publication. When works are subject to copyright outside of these countries, the term of such copyright protection may exceed the term of copyright inside them.
Unpublished works from Iran may be fully copyrighted.
A work from Iran may become copyrighted in the United States under the URAA if Iran enters a copyright treaty or agreement with the United States and the work is still under copyright in Iran.
Iran has enacted a copyright law which came into force on 12 January 1970 and communicated the official English translation to UNESCO on 20 April 1970.
The official position taken by the Wikimedia Foundation is that "faithful reproductions of two-dimensional public domain works of art are public domain, and that claims to the contrary represent an assault on the very concept of a public domain". For details, see Commons:When to use the PD-Art tag. This photographic reproduction is therefore also considered to be in the public domain.
