The Coming of Hopalong Cassidy
tells the story of when Bill "Hopalong" Cassidy became a man in the west to be reckoned with. In truth, at the beginning of the book, Hopalong is more than likely younger than 21 years, but is equipped with a man's body. He first travels alone, a youth undeterred by the perils of the West. The book was first published around 1908, long before the world came to know "Hoppy" on TV in the 1950, or in comic books around the same time.
