My signature is never really the same.
I have an everyday scrawled signature where I am certain I spell my own name wrong if I think about it.
I have a formal, this is an important document signature, that I use when I sign a passport or a legal document.
But they never really look the same. Napoleon certainly has a number of signatures. I am always interested to read what people have to say about Nappy. Some point out that the "more important" he became, the smaller his signature got. Interesting comment, but what does it really mean?
I think the experts are quite busy trying to authenticate all his documents.
What I would like to see is a favorite pen. No doubt the signature was effected by the tool.
