Looks like a scan from a book showing ladies how they should defend themselves in the event of an attack from behind.
Love the Drill Knee of Doom in number 4 on the right page and check that Sonic Slap in number 4 on the left page.
Speaking of number 4, I'm not sure a girl would knee a guy in the chest or the neck. She would simply just knee him in the nuts. Much more effective!
