Well, no he didn't say anything about the date.
He only said that he bought the autograph and that it comes with a COA, but this means nothing...
So, I think I won't take the risk and wait, till I see another (authentic) Clapton auto. I want him so badly, but can't pay high prices, so it's difficult but patience is the key
Thanks for your helpful comments.
Best,
Phil
