A reprint of the original, unedited 1923 text by Claude Hopkins. This groundbreaking book remains essential reading for anyone entering the copywriting and advertising professions, reminding us that advertising's purpose is purely to sell. Claude Hopkins expresses powerful, statistically tested truths about "salesmanship in print" which remain relevant through the decades and across all media - including today's internet marketing. David Ogilvy once said "Nobody should be allowed to have anything to do with advertising until he has read this book seven times. It changed the course of my life." Read "Scientific Advertising" before you read any other book on advertising or marketing. It may change your life, too.
