Campaign signs utilize a display envelope mounted on U-shaped frames. The U-shaped frames are folded prior to shipment so that leg sections of the frames overlie at least one another. The frames are generally sold as kits, each kit having a plurality of folded frames for ease of shipment. The kits may include a stack of bundle of folded frames alone or may include a stack or bundle of folded frames with a number of envelopes which are preferably folded or rolled in order to conserve shipping space. In one embodiment the kit contains a single folded frame and a single display envelope.
