Non Baseball But could use help - Sergeant York
 

Does anyone know value of a Sergeant York signature. I purchased this yesterday at a flea market. Has good provenance that the he was at a local high school. Didn't see much when I did a google search. I went ahead and listed it on ebay, but was wondering if this might be better at a large auction house. Any opinion or help would be appreciated. I don't suppose Sergeant York ever played in the southern league?

Looks genuine. York's signature is worth $100 or so.

Thanks, Dave . I wish the book was signed and not just a card attached.
