Roy Herbert Jarrett (1874-1937) was a Chicago sales executive and advertising man. After many years of studying metaphysical success methods, Jarrett produced the landmark pamphlet It Works in 1926. It has since sold more than 1.5 million copies. In 1931 Jarrett followed up his mind-power classic with his second and final book, The Meaning of the Mark, which served as the “inner key” to his earlier volume. Long available, The Meaning of the Mark is restored to print in this rediscovery volume.
