Abstract: A reversible book is provided having a front cover and a back cover and having pages in the form of a sheet in an accordian fold, the sheet affixed at one end to the front cover and at the other end to the back cover, and having a ribbon-like element anchored at one end to the front cover and anchored at its other end to the back cover, the ribbon passing through vertical slots in each fold of the sheet. The book has no spine, but is held together by the sheet and the ribbon element, on both sides of each of which may appear illustrations and/or a story. The reader proceeds through the book from front cover to back cover, reading material on the front of the sheet and ribbon, and then pulls the back cover around toward him and reads on with the same story or a new story, proceeding from back cover to front cover, reading material which was originally not in view being on the back of the sheet and ribbon first read.
