Hi b'ger,

Here's some additional info on this subject to be found. (URL dug up by
Andreas)

http://www.klab.caltech.edu/~seckel/triangle.html

On this page the first "impossible triangle" is ascribed to the French
artist Marcel Duchamp. In 1917 he made a pastiche on an ad in which the
wooden frame of the bed shows some "impossible" features.
