ABSTRACT:
An improved hanging display sign comprises boxes each having transparent e panels and a slot into which panels displaying letters are inserted to display a message. The letter panels are protected from inclement weather and from tampering by vandals by the transparent face panels and by sealing strips. A cable system is used to hold the boxes in a stack, with each box closing the opening in the top of the box below it. Drawing the cables tight holds the boxes together in a stack to form a weatherproof, vandal-proof display sign.
