[edit] Summary

One of Donald Knuth's reward checks. Note that the machine-readable numbers at the bottom of the check have been randomly swapped or modified, so that no personal information about Don Knuth's personal bank account is leaked through this image.

The check itself was scanned by Schutz as Image:Knuth-check.png. The logos and design on the check have been pixelized by Simetrical. Both Simetrical and Schutz believe that the remaining content is not sufficiently original to warrant copyright. However, in order to be on the safe side, the image is used in Wikipedia under a fair use rationale

[edit] Licensing

This work is copyrighted and unlicensed. It does not fall into one of the blanket acceptable non-free content categories listed at Wikipedia:Non-free content#Images or Wikipedia:Non-free content#Audio clips. However, it is believed that the use of this work in the articles "Donald Knuth" and "Knuth reward check":

To illustrate the subject in question
Where no free equivalent is available or could be created that would adequately give the same information
On the English-language Wikipedia, hosted on servers in the United States by the non-profit Wikimedia Foundation ([1]),

qualifies as fair use under United States copyright law. Any other uses of this image, on Wikipedia or elsewhere, may be copyright infringement. See Wikipedia:Non-free content and Wikipedia:Copyrights.

To the uploader: this tag is not a sufficient claim of fair use. You must also include the source of the work, all available copyright information, and a detailed non-free use rationale.

If the image is subject to copyright, I (Schutz) feel it is covered by the U.S. fair use laws when linked from Knuth reward check because:

Its inclusion in the article adds significantly to the article because it shows the subject of this article, which is a significant topic in the computer science world;
The image is only being used for informational purposes;
The image of a cheque has little or no commercial value, so that its inclusion in Wikipedia does not affect its potential market or value;
There can be no free image of such a cheque.

I have pixelized the two logos on the check, as well as the designs in the upper corners; thus, there is no remaining content that is sufficiently original to warrant copyright.)
