AL/NL Ball ID Guide

[brewcrewfan77]

A year or so ago I saw a book on the boards about, for lack of better words. the history/evelution of AL/NL balls. I believe it came in two volumes one for each league. Does anybody know the book and if it's still available? Much thanks for any help.

Here you go. Both volumes are excellent in my opinion:
