An elongated sign holding extrusion for supporting a sign from an overhead member, comprising an elongated unitarily extruded frame assembly having an upper edge and a lower edge, with a first side portion and a second side portion extending therebetween. An elongated upper receiving-channel is arranged at the upper edge of the frame assembly. An hollow elongated, upper channel is arranged in a spaced-apart, adjacent and parallel manner to the elongated upper receiving channel in said frame assembly. An elongated middle channel contains a pair of elongated biasing members therein for pinchably supporting a poster therebetween. An elongated central channel is spaced adjacent the lower edge of the frame assembly for capture of slidable sign supporting hangers.
