Abstract
An erasable graphic panel includes a substrate having a dark surface, a translucent film overlying the substrate and adapted upon application of pressure from a pointed implement to adhere locally to the substrate and thereby produced a visible trace of movement of the pointed implement upon the film. The panel also includes a slider positioned over the substrate and having a lifting blade extending under the film and being movable across the substrate to lift the film and thereby erase the visible trace.
