"Although specifically designed for the anti-nuclear movement it has quite deliberately never been copyrighted. No one has to pay or to seek permission before they use it. A symbol of freedom, it is free for all. This of course sometimes leads to its use, or misuse, in circumstances that CND and the peace movement find distasteful. It is also often exploited for commercial, advertising or generally fashion purposes. We can’t stop this happening and have no intention of copyrighting it. All we can do is to ask commercial users if they would like to make a donation. Any money received is used for CND’s peace education and information work."
