ABSTRACT:
An indexing system for signs consisting of a plurality of indicia bearing vane faces wherein the vane faces are sequentially exposed to view in the manner of a "wave", such sequential revealing of the sign vane faces generating interest in the sign's message. Each sign vane is rotated by a transmission and the transmissions are interconnected in such a manner as to sequentially operate the vanes to produce the "wave" action and detents associated with each transmission lock the sign vane in the desired position.
