Incredible publication from 1914 produced by the Baseball Correspondence League of America is a veritable bible of pitching knowledge from some of the great hurlers.  The 48-page book is completely photo illustrated with individual "lessons" written by the likes of "Doc" White, Christy Mathewson, Walter Johnson, "Nap" Rucker, Joe Wood and Ed Walsh.  A tear in the top part of the spine keeps this book from being NRMT.
