Fine, I should have said patented instead of invented. Regardless, it wasn't in commercial use when Charles Comiskey, the HOFer passed. Comiskey's Grandson had the exact same name and middle initial. He was also owner of Chicago White Sox. He passed away less than ten years ago, and his autograph retails for around $50. I have no idea the added value since this is a "1/1".
Technically, the back is a bit deceiving, as it Left out the "II" in his name, but is otherwise correct.
