I would recommend you get the paperback version, because, lets face it, you don't want to spend too much on a book, and it's simply just a waste of money to get a hardback.
Going back to the quality of John. F. Grabowski's work- It has good, understandable language, and the titles of sub headings are really professional. For example-
"The Boy Who Would Be Lion King, and "The Life Of A Star." Jonathan Taylor Thomas is truly amazing, and with this guide, you will see that the handsome young actor is even more stunning then when you first set eyes on him.
It is a great book for sketching from. Trust me, this is no ordinary book, you will immediately be on the hook. Happy reading!
