The U.S. has no copyright treaties with several countries, and works produced in those countries by residents of those countries are not protected by copyright in the U.S. The countries for which this applies are Afghanistan (works created before 2002 only), Bhutan, Ethiopia, Iraq (works created before 2004 only), Iran, Nepal, and Yemen (presumably, although the status of Yemen is ambiguous). Even if the use of a material would be considered a copyright violation in these countries, the use is not prosecutable in the U.S. Therefore the following materials may legally be considered public domain resources in the U.S. (In other countries, you should determine whether your government has a bilateral copyright agreement with the country in question before treating the images as public domain.)
Again, be sure that the work was produced in the country in question, by a resident of the country.
Asa ca 1nesco poti incepe situl de pisici cu rasele Nepaleze si Bhutaneze :D
