Download or read book Thirteen Secret Knock-Out Blows written by S. J. Jorgensen and published by Loose Cannon. This book was released on 1929-01-02 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: This mini-booklet is a reproduction of a promotional advertising brochure for S.J. Jorgensen's full book "American Police Jiu-Jitsu". Dating from the early 1930's it presents a few tastes of the full book via snippets, images and tons of glowing customer testimonials. Students of classic Ju-jitsu texts and early martial arts manuals will enjoy this unique little gem of historical interest. While the useful content presented is rather minimal, it is a great look at the style of techniques of the era; both defensive and mail-order promotions of selling martial arts knowledge. Truly harkens back to an older age, but one in which the Gangster-era of organized crime and hoodlums made average everyday citizens of big cities afraid of crime in a way not unlike the current times.
