How to Throw curves is in the roughest condition with spine tears and a missing upper right corner but the book is complete and the cover is attached. How to play the outfield has some staple rust and a light pencil mark by the fielder's forward knee, How to Play the Infield is very nice with some light soiling to the blank back coverand How to Knock Home Runs has some spine ticke and stray pencil at and under the facsimile signature.
