摘要：
A support for an outdoor sign has an upright where an upper and lower extent are swingably connected to move between an erect position for use and a collapsed position for storage. A cross-bar is pivotally connected to the upright for movement between a perpendicular relation to the upright, for use, and a collapsed position for storage.
