The strength of this book is the abundance of photos for each form. The photos are also numbered according to the corresponding step in the form. Several of the more complex steps have multiple photos (6a, 6b, etc.) showing intermediate positions moving from one step to the next. The story behind the form and notes which precede each form are far superior to the "one liners" that usually accompany the forms.Parts of the book are a little cheesy, however. A section showing Master Cho on various martial arts magazine covers does nothing to add to content. The biography was a little melodramitic.Fortunately, the heart of the book is very useful, making this book valuable to those practicing the ITF Hyungs.
