Book collecting is big. Especially valuable are first editions. Disney collectible books include individual books with Disney characters and also, sets, such as the Mickey Mouse Collection of 12 little Golden Books.
In addition, books with a record, such as a vintage 1960 Bambi album, are available. There are books about the history of the Disney Corp. as well. Rare Disney comic books are harder to find.
One popular Disney book is Warmans Disney Collectibles Field Guide. This book introduces beginning collectors to the world of Disney collectible items and how value is determined. Look for this item and other Disney collectible books on eBay.
