Abstract of the Disclosure A sign is made by a pultrusion process by printing separate sign panels and attaching them to a fibrous component of the sign to make a longitudinally continuous sign panel subassembly which is beneath the surface of the sign. The sign panels are spaced apart in the subassembly by about the length of the sign and are fixed to the fibrous component prior to being pulled through a forming die. In the forming die, the subassembly is formed together with rovings, scrim resin and any other components of the sign into the cross-section of the sign. The sign panel subassembly saturates with the resin so that it blends in with the rest of the sign except for identification matter printed on it and is permeable to allow gases to escape as the resin cures in the die. The sign takes on its desired cross-sectional shape in the die and is cut off at its desired length after it exits the die. The sign panel may be on either side of the subassembly, and the subassembly may be beneath a surface layer. The fibrous component of the subassembly may be continuous, or may be in sections spaced apart and affixed to the sign panels. A double sided sign may be made by attaching pairs of sign panels side by side to a fibrous component which can be folded to display the sign panels on both sides of the sign.
