The broad scope is both educational and recreational, adding a new dimension to this popular collecting subject. Within these books, readers will find coverage of the historical background, manufacturing techniques, construction information, actual basic patterns, variations and rarities, the art of collecting, and a wealth of other salient facts of absorbing interest.
