I have always been interested in Shoeless Joe Jackson’s signature. I would assume they are pretty rare. Has anyone done a signature study? Does anyone have an authentic example?
Jackson was illiterate. The only way he could sign his name was to copy it from one his wife would sign. He would then draw it. If you look at authentic versions, you can see how shaky they are because of this.
The contract cut (if it's a cut or just a crop) has what I think is clearly Charles Comiskey's signature. The Joe Jackson signature looks very much like the others I've seen with strong provenance.
