Close call, it's hard to read since there is no enlarged photo of the actual signature.
However, I think the penmanship letters are too small for his style, even though they are slanting to the right which is a good sign (he was left handed).
Sorry I can’t make out the top image very well. I don’t like the ‘Michael’ on the second image. It has no fluency. Looks like it’s been copied so I would be steering clear
