摘要 |

A generally rigid board shaped in the form of a pennant has visual indicia on one or more sides. The board is hingeably attached to a cross-arm which in turn is secured to a structure such as the pole. The preferred construction of the board is a structured plastic for purposes of rigidity, durability, and environmental longevity.
