A book shaped educational amusement device has outer covers that can be moved between open and closed positions. Three dimensional removable educational material and a message carrier such as printed sheets making reference to said educational material are disposed near each other, each on a respective cover. The material and said printed sheets in the closed position of the covers are positioned laterally relative to each other while the material projects with its face beyond the confines of the collected printed sheets towards the outer surface of an opposite cover.
