Abstract
A signpost comprises a base adapted for being driven into the ground, a vertical post member fitting over a portion of the base extending above the ground and into a collar on the base, and a horizontal post member from which a sign is attached being connected to the vertical post member. The base is easily removed from the ground by the use of a fulcrum and a lever arm to which a ring is attached. Placing the ring over the upper portion of the base and forcing down on the opposite end of the lever arm pulls the base from the ground.
