Abstract
An escalator or travelator is provided with a plurality of advertising signs on the riser or step of the escalator or travelator. The sign is provided with a transparent cover which is positioned on the step so as to not interfere with the relative movement of adjacent steps on the escalator/travelator or the cyclic movement of the escalator/travelator itself.
