very interesting book. was one of those you do not want to put down. it gave a different perspective of the happenings of the manson family. however, one must keep in mind it was recorded from what charles manson believed happened. great book.

Positive

I grew up on these books and the biggest part of their allure and charm was the nightmarish and frightening artwork by Stephen Gammell. I am EXTREMELY disappointed that they are being re-drawn with a washed out and flowered up style. Please take my advice and buy the original, it is definitely worth it, I promise. I think it is sad that some children will never know the original drawings because parents are too uptight and make a big fuss about them. Too sad. They are SUPPOSED to be scary, you know?

Although I was excited to purchase this book, my excitement didn't last when I looked at the sketches / pictures in the book. I call them pictures because that is what they truly are, not actual patterns. Norma Gregory's talent shows up well in her designs but due to their complicated rendering they are very difficult to transfer.This book is not for beginners - but more seasoned artisans.If you are looking for patterns, like I was, you will be disappointed in this book.
