In Poland, copyright is regulated by the act from 1994. The first Polish copyright law act has been enacted in 1926 (although copyright issues have been regulated on territories of partitioned Poland in the 19th century by governments of the German Empire, the Russian Empire and Austro-Hungary, beginning with the 1828 copyright law passed in Tsarist Russia). Poland signed the Berne Convention in 1919, soon after regaining its independence in 1918. The main acts that have regulated Polish copyright law have been: Polish Copyright Law from 1926 (Polish original, amended version from 1935) (Dz.U. RP 1935; Pos. 260) Polish Copyright Law from 1926 (Polish original, amended in 1952) (Dz.U.52.34.234) Polish Copyright Law from 4 February 1994 (Polish original) (Dz. U. nr 80 z 2000r. poz. 904) Polish Copyright Law from 4 February 1994 (English) Polish copyright law complies to a large extent with legislation in European Union, see EU Copyright Directive. 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 (or published for the first time in Poland or simultaneously in Poland and abroad) printed without a clear copyright notice before the law was changed on May 23, 1994 are public domain. Status of those photographs did not change after Polish Copyright Law of February 4, 1994 was enacted.

However, in some instances the use of this image in Poland might be regulated by other laws. It is being debated if postage stamps fall into this category. (See: Template:PD-Polishsymbol) According to the Art.21 of copyright law of March 29, 1926 (valid until 1952) photographs lose copyright protection ten years after picture was taken.
