According to the Art.3 of copyright law of March 29, 1926 (valid until 1952) and Art. 2 of copyright law of July 10, 1952 of the People's Republic of Poland, all photographs by Polish photographers printed without a clear copyright notice before the law was changed on May 23, 1994 are in public domain. Status of those photographs did not change after Polish Copyright Law of February 4, 1994 was enacted.
According to the Polish Copyright Law of February 4, 1994 (Article 4, case 2) "governmental symbols, documents, materials and signs are not subject to copyrights". According to the Art.21 of copyright law of March 29, 1926 (valid until 1952) photographs loose copyright protection ten years after picture was taken.
