Abstract: A large sign mounted high on a supporting pole, tower or building is provided with changeable figure sections. Each changeable figure section includes an upper motor driven roller and a lower motor driven roller and an elongate panel of flexible material having digits 0 to 9 thereon with opposite ends of the panel fixed to and rollable on the respective rollers. A three wire motor control system is provided for each changeable figure section that extends therefrom to the ground and on to a remote location with a two way switch where the operator can watch the sign changes he is making. This makes it easier and safer for a person to change letters and numbers on billboards that are dangerous and/or inaccessable to climb up on and work on particularly with a sign high in the air facing the elements.
