Charlie Ganzel Diamond S
 

I've had this card in my collection for about 7 years. I was looking at the writing on the front and it looks like someone signed his name in the way a player might autograph his own card. The spelling on the pencil writing is corrected from the card.

Are there any examples of his signature? This card was sold as poor with markings through the regular market i.e. I bought at auction through one of the regular houses, but don't remember which one.

I don't want to sell, as I'm slowly working on the set. Any thoughts?
