This book came out a long time ago. I read it when it first came out and it introduced me into the world of ghosts and and lore. I was 12 years old then in 1982 and even now when I pick it up to read....it still takes me back to the feeling...when I first picked it up and sent shivers down my spine...in a fun way of course. The stories and the drawings were perfect together. A great book. I have all 3 volumes now and I hope he comes out with a 4th one soon.Thanks Alvin and Stephen for scaring the pants off of me when I was 12.

Purchased from We Sell Bulk here on Amazon and received the item much faster than predicted delivery date - I only say that because there's always a list and it's often difficult to pick which seller is the one to go with. Anyhow, the battery came in original and undamaged Canon packaging (looks just like the images available in product description). I was not about to buy the cheap knockoffs and was worried that the one I ordered would be any different than the one that came with the camera (damaged item or store return). Well, after a couple charges and hundreds of pictures, I can say that this battery is exactly the same as our original. It lasts just as long and charges in the same amount of time. Our camera is fairly new so it was a fair comparison - one battery wasn't all that much older than the other.Email me with questions: mister_mr_d@hotmail.com

It was a very good book. It explains in full detail the history of Goju-ryu karate. It also has step by step instructions for katas with black and white pictures. Almost every page has a picture. This book also has a glossary with the Japanese terms translated from Japanese to English and English to Japanese with the phoenetic pronunciation. Motoo Yamakura is a very good martial arts writer.
