I know nothing of autographs, so no intent to throw fuel on the fire, but I will say that I have the worst handwriting of anyone I know, and I am admittedly embarrassed and uncomfortable with my signature. It has changed significantly over the years and today varies notably fom signing to signing. I recall purchasing one of my homes and filling out all the mortgage and legal documents, and the lawyer asked me to do it all again because my signatures varied so much.
To me the photo and draft card are not that significantly different, or at least reasonable that the same person could have done them.
