A scrolling billboard having a frame, a first pair of mandrels mounted within the frame supporting an elongate banner having multiple sign images. One sign image is viewable within the frame opening. A pair of sign drive motors are connected to the first pair of mandrels. A second pair of mandrels move a curtain relative to the frame opening between a blocked position where view of the sign is obstructed and a viewing position in which view of the sign is unobstructed. The mandrels are tubular and internally supported by mandrel supports to prevent sagging. A controller cooperates with the sign and curtain drive motors to change the viewable image by: moving the curtain to the closed position, changing the sign image, and returning the curtain to the viewing position. An add/remove fixture is disclosed to insert or remove signs from the banner. A corresponding method is also disclosed.
