Thoughts on a Dizzy Dean...

[Mr. Zipper]

I'll preface this by stating Dean is not my area of expertise, so take this for what it is worth...

Overall this signature appears to have a hesitant, tentative look. It's hard to describe, but I see "too much thinking" in it.

There is obvious wobble throughout both Ds. They were not executed smoothly and have an unusual "boxy" shape.

The "izzy" starts with a hard dot (hesitation) and the pen only sped up when he hit the "home stretch" ... the final loop of the y.

One could argue that it is an "in-hand" standing signature. Maybe that is the case, but the wobble I see here doesn't strike me as the same kind of shakiness you see with an in-hand signature.

I cannot state with certainty, but I think there is a valid case for reasonable doubt.
