So I'm browsing and I stumble across a book entitled Real Grass, Real Heroes by Dom DiMaggio. Dom is the brother of Joe, and had a decent baseball career in his own right playing in the same outfield as Ted Williams. In fact, the book is about that last fateful year of major league baseball before World War II came crashing down on the United States' head. I'm a baseball fan in general anyway, and it'd be interesting to see what Dom had to say about the game back then, so I buy it. Fifty cents.
I get it home and set it aside, meaning to get it cataloged into LibraryThing before I put it on my shelves. It sat next to my bed untouched for a few days, and then I pick it up to catalog it. Its ISBN doesn't match anything on Amazon, so I query the LoC on the title, and in checking to make sure my copy matched, I find a note handwritten in it.
"To Gene, Best Wishes. (signed) Dom DiMaggio"
Checking the signature against items verified signed by Dom on Ebay confirms that this is very probably his signature.
Holy freaking crap. %)
