ABSTRACT:
A free-standing rolling book comprises plural sheets, bound along one marginal edge. In the preferred embodiment, the book cover includes printed matter depicting a wheeled vehicle having wheel wells disposed adjacent the bottom edge of the book. Respective wheels are rotatably cantilever mounted at each of the wheel wells. The dimensions of the sheets and the wheel span of the wheels are selected such that the wheels support the sheets in a free-standing position so as to permit the book to roll without external support. The wheel span should be at least two-sevenths of the distance between the center of gravity of the book and the wheel-supporting surface, and, in the preferred embodiment, is one-seventh of the book's height.
