This image is a faithful digitisation of a unique historic image, and the copyright for it is most likely held by the person who created the image or the agency employing the person. It is believed that the use of this image may qualify as fair use under United States copyright law. Other use of this image, on Wikipedia or elsewhere, may be copyright infringement. See Wikipedia:Fair use for more information. Please remember that the non-free content criteria require that non-free images on Wikipedia must not "[be] used in a manner that is likely to replace the original market role of the original copyrighted media." Use of historic images from press agencies must only be of a transformative nature, when the image itself is the subject of commentary rather than the event it depicts (which is the original market role, and is not allowed per policy).

If this tag does not accurately describe this image, please replace it with an appropriate one.

Fair use for Tsar Bomba and History of the Teller–Ulam design[edit]

The image linked here is claimed to be used under fair use as:

1. it is a historically significant photo of an important event;
2. it is of much lower resolution than the original (copies made from it will be of very inferior quality)
3. the photo is only being used for informational purposes.
4. Its inclusion in the article adds significantly to the article because it depicts one of the most important milestones of the project
5. The photograph belongs to Russian department of Atomic Energy Minatom. Introducing the picture on our server does not interfere with their ability to develop and market new nuclear devices
