File:20 Korun 1941 obverse.jpg

This work depicts a denomination issued by the Czech National Bank, which is not subject to copyright protection as it is an official work and there is public interest in its exclusion from copyright protection. This does not necessarily apply on such coins which are not official works (privately issued commemorative coins etc.).

The Act No. 136/2011 Coll. and the decree of the Czech National Bank No. 274/2011 Coll.(engl. version) define the terms and conditions under which it is possible to reproduce money:

For intangible reproductions of banknotes, it is required that their resolution does not exceed 72 dots per inch and they are marked with the word “Specimen” printed diagonally in an opaque colour and in a layer that cannot be separated from the image of the banknote, with the length of the word being at least 75% of the longer side of the banknote and the height being at least 15% of the shorter side of the banknote (or with another word of the same dimensions and similar meaning). Intangible or nonmetallic images of coins may always be produced.
