Both in excellent, like new condition. Rare to find both together in such great condition. Published in 1989 for Discovery Toys. This hardcover book with extra thick pages for durability helps children to learn about different types of musical instruments and activities and encourages readers about the joy of "music-making". The cassette tape, published by Child's Play International, includes the story with background music on side 1 and the musical score on side 2 (great bedtime music).
