Here is the original pick up manual which was first published way back in May 1970. It has since been updated a couple of times:
How to Pick Up Girls!: Eric Weber: 9780914094432: Amazon.com: Books
It teaches indirect game by the way. Here is a short sample of what it tells you, giving a few of its indirect openers: "How do you cook a leg of lamb? (You've spotted a pretty chick in your grocery store.)
Who's your dentist? (You want to know how she came by such beautiful white teeth.)
Where did you get that marvelous coat? (Tell her you work for a clothing company and think her coat is absolutely terrific.)
Fantastic book! Have you got to the part where the butler murders himself? (The sexy girl sitting next to you on the bus is reading a book you've just finished. Or even a book you've never heard of.)
I'll bet your name is Lisa. (To you, she looks like a Lisa. Pretty and sexy.)
I love you. (To be used half in jest at parties and in singles bars.)
I'm writing a book on picking up and I'd like to ask you a few questions. (I found this to be the picking up line of them all!)"
You have to remember this was perhaps the very first manual about seduction so don't expect too much from it. Before this though there was a British film called "The Knack and How to Get it" from 1965 which touched on pick up slightly but didn't go too in-depth.
