Abstract: A shuttle display apparatus including a base formed with multiple sets of pairs of parallel lateral tracks connected together on their opposite ends by respective longitudinal shuttle tracks. Display panels are racked together for translinear travel progressively in such lateral tracks to selectively display, in coplanar relationship, the respective front sides of a pair of such panels in one direction and to thereafter selectively display the back sides of such panels in coplanar relationship in the opposite direction. A drive is provided for automatically advancing a pair of panels along a pair of lateral tracks and then shuttling one panel of the pairs to an adjacent pair of lateral tracks to dispose such pair of panels abreast of one another in a coplanar displaying position for displaying composite messages in one direction or another.
