Anything by Bruce Tegner.
Books by Bruce Tegner are classics.So well illustrated eg.How to stop a mad guy from splitting you in two with a immense axe or crushing a dogs rib cage[was the dog mad? answer the dog was not very pleased]Old joke.I have an original red book by this early pioneer of japanese mayhem.I wolud not part with it for love nor money [well maybe 10 dollars or a peck o the cheek might persuade me otherwise].
My own favourie book on Aikido is the book by Tamura Sensei written in french.Superb.Aido in daily life , by Tohei Sensei is imo excellent. Cheers, joe.
