A display device for displaying advertisement cards in turn has a pair of inclined surfaces which support a rod attached to each card. The cards slide downwardly and forwardly and the front card is picked up, thereby exposing the next rearward card to view, by a pair of pick-up elements carried by endless loops. The loops are driven round a circuit. Parallel guide rails are provided to preclude tilting of the elements.
