A PANORAMIC DISPLAY.
The mechanical feature attached to this dress goods display consists of a frame in the center of which appears a panorama of bright pictures, portraits of prominent men, etc. The frame is made of ordinary boards and puffed in two colors. In the picture shown there was an electric light in each corner of the frame. Within the frame the panorama moved constantly from top to bottom.
The panorama consists of pictures fastened together endwise upon a belt of ticking and forming an endless band about two 7-inch rollers, which are placed at the top and bottom of the background. As the rolls revolve by means of an electric motor, the pictures pass across the frame.
