Recently, I came across an old goju-ryu karate manual that was published in 1982. The author was a Canadian man; a Nidan who had trained for 15 years at the time the book was published. The book is filled with high quality photographs of kata moves. It’s quite thorough; with each kata sequence recorded frame by frame, along with a detailed description of each block and strike. In a time before Youtube, a book like this would be the only way for someone to learn kata moves
