A display device including an image selector, for selectively displaying images of a multi-image indicia carrier, a back board, a motor that provides relative movement between the back board and the image selector and an indicia carrier detachably placed between the image selector and the back board, such that it moves with the back board, at least partially due to a non-interlocking coupling of the indicia carrier to the back board. |
