Congrats!! This gives me hope (especially as you said it's likely to be authentic) as I sent to him a couple of days ago and wasn't 100% sure if he signed or not.

Now the awesome HP movies are done he might have a chance to answer mail more but dont be surprised to wait a few years. He must have a few mountains worth of letters waiting.

Congrats!! I wrote in 2007 I think but never heard anything back

I thought he wouldn't reply...Maybe i'll try too.

Congrats

Two years ago with Mr Isaacs being so busy I wrote him a little note sure he would be driven crazy how everyone would go on about Harry Potter at him so I talked about his earlier movies and the joy they bought me, i didnt ask for a picture or anything sure he`d be snowed under. Today he sent back a signed colour pic and awesome letter answering some of my questions so he must have read it and the sig looks genuine. The films might be over but the stars still shone on.
Sorry, no scanner.
Best.
