There has to be atleast 1 Van Morrison expert here
Here's the one I got from him in Dublin at a gig.
That is, his PA brought it in and got it signed for me - on condition that I didn't approach Van...
He's very very difficult :P
The sellers inventory is a mixed bag. Much of it seems legit, but some aren't even good forgeries and certainly weren't obtained in-person as stated.
Perhaps he has untrustworthy runners, as some of his signing photos show "lesser" stars signing stacks of items with obvious forged autographs of the "bigger" stars already on them.
