Your decision has already been made, but
Here's my autograph book that I used during 1957 spring training in Clearwater, Florida.
As a 9 year-old I was able to obtain nearly 100 autographs after the games. Not many of you can say you met Casey Stengel and Roy Campanella before he was injured, but they are both in there. I haven't carried it with me for 68 years, but my mother saved it (,but she didn't save my cards

)
I'm keeping it intact with Casey, Roy, Alston, Ashburn, Minoso, Killebrew, Snider, Newcombe, Furillo, Kuenn, Doby and even Al Cicotte (related to the 1919 World Series star) just to name a few.
If I sell it, it would likely be broken up, and I understand that, but it will not be done by me.
The sentimentality value vastly exceeds the current cash value of the book.
I didn't pay a dime for any of the signatures. Is there a nine year old today with a similar collection for any price? I think not.
