Graphology

What can we learn of personality from a signature? Very much I think. 

I'd deduce that the writer of the first signature is honest, open, rounded, generous, confident, well-balanced and has a good sense of humour. 

I'd say the second example shows the signee to be untrustworthy; the theatrical combines with angst ridden egomania to create a perilously unbalanced mind. There are definite signs of a  depression which could end in self destruction.

But I'm no expert. And graphology after all is a disputed science.

So here's an interesting puzzle. Who signed these autographs? 

The identities, if not immediately obvious, can be found in microscopic type at the bottom of this posting.
