Deep in the saddlebags that contain all the Hopalong Cassidy prose, motion picture, comic book and newspaper comic strip stories there are often-forgotten nuggets: 104 half-hour radio adventures which hold up as well today as when they were first broadcast in 1950-52. All of the episodes survive and are available in audiotape and MP3 formats for the avid collector or casual listener. JINGLE OF THE SILVER SPURS examines the Mutual, and later CBS, networks series, its background, its producers, its performers, its writers, its sponsors, its storylines, its merchandising in detail seldom seen in histories of old-time radio shows. Illustrations include rare advertisements, photographs and press kits. Foreword by Western author, Loren D. Estleman.
