English: This figure is the simplified outline of a drawing by Roger Hayward from an article on "Blivets: Research and Development" published in The Worm Runner's Digest (December en:1968) and reproduced in en:Martin Gardner's Mathematical Circus (Pelican Books en:1981, ISBN 0 14 02.2355 X). Hayward's version shows a stone monument with its two (or is it three?) legs standing in a lake, thereby concealing the details of the bottom of the legs which would otherwise have committed him to deciding on their number.
Specific drawings such as Hayward's are copyrighted, but the simplified outline in blivet.png has been repeated in so many places that it can be considered public property.
