I became interested in handwriting analysis about 20 years ago and started learning as a hobby. I'm not an expert at all and never went to school for it but I can say there is something very revealing if this truly is his real signature. Everything from the brain goes to the hand. This signature is vague. And it gives no details. It tells nothing other than a fairly calm demeanor. I'm sure there are reasons for the smaller middle part but for the most part, it is vague. Does this not sound like what a treasury secretary (or Fed chairman) would be like? Give no details. Be vague. At least to the American people. It's not a surprising nomination.
