This book by Mary Ann and Wolfgang Sell gives a historical overview of View-Master items. In particular, viewers and other rare items are covered. This book was originally supplied with 6 view master reels. However, the fourth and fifth reel are sold out, therefore this great book is now offered as a bargain, with 4 reels. The reels show some of the rare view-master collectables that are mentioned in the book. A 3D presentation of unique View-Master items!
