Chessvibes are reporting on an auction of Bobby Fischer's handwritten notes from the 1970 Herceg Novi Blitz Tournament. This event was significant, as it was probably the strongest blitz event held up until that time, and Fischer won with an emphatic 19/22. Famously, he then recited all the moves of each of the games (or so the story goes).
This collection of notes covers 8 of those games, and the notes are being auctioned by the son of the tournament organiser. At the time of posting, the current bid is 2,167 pounds, and the auction closes in 8 days. I suspect the final bid will be over the 5,000 mark, which probably puts me out of the running.
