There was a cool story behind this too that I think might help determine when it was signed. The book store I'm buying this from got it from the lady who me this book was signed too and she said that she went to the race track and found Buk and that he was in a good mood and signed it for her with the inscription. I always wanted just one book of his signed and this inscription made me buy it. Thank you guys so much for the responses! And another question...is that inscription itself rare? Has it been written in other books before?
