Claude Hopkins was an advertising genius earning $185,000 in 1907 as an employee of an advertising firm. That's equivalent to $25.7 million today. Claude codified his techniques in 1923 in a book called Scientific Advertising. While this book has been recommended and used by many great advertising minds since Claude's day, his principles still remain broadly unknown. To ensure Claude's techniques and principles are not forgotten, best-selling author and entrepreneur Tony Melvin has taken Claude's original work and isolated 114 Marketing Laws that apply today. Never before has Claude's work been presented with such clarity. If you learn and apply these laws, you'll never waste money on ineffective advertising or marketing again. That's a promise!
