[sửa] 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
