I can't - but check in the "Signatur" topic - members over there can probably tell you not only the year but also the day of the year the signature was done , by only looking at it ;D
That is really impressive
Edit: im definitiv out of my comfort zone here, but it doesn't look like the recent once (2010+)
but here I am out - there is a topic somewhere that shows the sig over time - searching for it right now
Condition of the book is up for your judgement, its so subjective, anyhow its a very nice copy!!
If its yours congrats - its a treasure to have such a nice book.
Edit: - i put me bet to mid 90' for this one ;D
