A vehicle-top sign display assembly which is constructed to support a pair of signs in arched back-to-back relation. The assembly includes a pair of corner supports which accommodate opposite vertical edges of the signs in sandwich relation with a pair of wedge-shaped members interposed internally between the signs. A pair of spreaders are disposed transversely across the top and bottom of the assembly to maintain the centers of the signs spaced apart. Each of these includes two pairs of grippers which accommodate the upper and lower horizontal edges of the signs.
