Z Kornin: This is a well known h#2 by G. Paros, and Sonnenfeld found a slight constructive improvement... The question is : "What happened?" Felix died early in 1993, and evidently somebody - perhaps not whith the required expertize - scrambling and stiring in his remaining papers, saw this diagram and concluded mistakenly that here was an Original FS still unknown! I knew Felix personally, if only en passant, and also by mail exchange: a gentleman and homme d'esprit - and more, a true Artist - enjoy his legacy, and please forgive this example of excessive zeal from his followers! - better reading "G. Paros, version by F. Sonnenfeld" (2005-2-6)
