This image shows a flag, a coat of arms, a seal or some other official insignia. The use of such symbols is restricted in many countries. These restrictions are independent of the copyright status.
This image is in the public domain because according to Article 4, case 2 of the Polish Copyright Law Act of February 4, 1994 (Dz. U. z 2006 r. Nr 90 poz. 631 with later changes) "governmental symbols, documents, materials and signs are not subject to copyrights". Hence it is assumed that this image has been released into public domain. However in some instances the use of this image in Poland might be regulated by other laws.
(Tiny edits to the shield, mostly it can hit the edge of the canvas. I still don't know why it appears shorter on the right side, but it was a direct copy from the left side.)
