Nice to see some of these techniques in action, particularly in that the self defence section of The Wrinkle Book was possibly my first ever exposure to the notion of “early 20th century martial arts/self defence”. My late father had a first edition copy of this book and I came across this section while leafing through it sometime in the late 1970s or early ’80s; note to younger people, this is the sort of thing that sometimes happened long before the Internet.
Much later, the Wrinkle Book‘s page of self-defence illustrations may well have been the very first image I ever scanned for online republication, and in 2006 I used a lightly modified version of the same page as the cover image for my augmented republication of Andrew Chase Cunningham’s book, The Cane as a Weapon.
