Abstract
A book having a sound producing capability which attracts the attention and interest of children and which does not require batteries or another source of electrical power. The book has a hollow spine or binding defining a conduit which slidably contains a noise making device, such as a whistle, therein. In the preferred embodiment, the spine of the book is a hollow tubular member which slidably receives a member which produces sound as it slides through the tubular member, under the force of gravity, due to the forced passage of air through tortuous paths and/or constricted openings or slits in the member (e.g., as in a whistle or the like).
