How are you? We will have to catch up one of these days
For your best opinion on Eastwoods autograph, I would go to the forums of clinteastwood.org and ask your question in the collectors corner section. There you have Eastwoods biggest fans and many have gotten his auto in person and can give you the best opinion on the graph you are looking at
Take care
