Abstract: A portable sign apparatus has a changeable display and includes a frame having a pair of vertical frame members and a pair of horizontal frame members attached to the vertical frame members. A display portion is removably attached to the frame between the horizontal frame members. A ground support base is attached to the frame to support the frame in an upright position for displaying the display portion and supports the frame at each end thereof with a pair of legs connected to a leg support member. An attaching system allows the frame to be movably attached to the leg support members to allow the frame to be raised and lowered. A ground support attachment provides additional support between the frame and the ground to hold the sign more securely in position.
