Cheers for that Green. I have started to read Henry Coopers Tackle Boxing book. Its his how to box book. Very good. Written in a different style to Dempsey, with much more modern approach. In the sense that he places more importance on certain punches used in todays boxing ring then what Dempsey did. Notably the jab. It has fantastic photo's of champs doing the punches in contests. He also for each punch gives a pro-tip. With some cracking ideas. When needed he also uses drawings like Dempsey. I high recommend this book.

In the end after researching online, went for Henry Cooper : An autobiography by Henry Cooper written in 1974. It gets good reviews. Where as the modern one only gets average reviews.
