Abstract
The present invention comprises an elongated extruded poster clamp support assembly for the stiff and reliable hanging of a poster or sign therefrom, comprising an elongated planar base having an upper edge and a lower edge, a channel arranged on the upper edge of the planar base, to permit the clamp to be supported, and a pair of elongated legs attached to the channel, the legs arranged to be rotated into a poster holding orientation by movement about a hinge extending from the channel. The legs thereby define two spaced apart pressure strips biased against the base, for the pinching of a poster therebetween. The invention includes an elongated groove arranged as part of the channel, for the receipt of a stiffener rod to help keep flat any poster supported in the clamp.
