Abstract
A portable sign stand with wheels or rollers, an adjustable weighted base member, and a sign display member. The base member has one or more compartments so that liquid or solid ballast can be added to stabilize the sign stand in windy conditions. The upper and lower wall members of the otherwise hollow base member are joined together at one or more locations where the sign display member is connected to the base member. The base member can be made by blow molding techniques. Wheels are provided on one edge of the base member in order to allow the sign stand to be rolled and easily moved to different positions. Axle members secure the wheels to the base member. One or more resilient members can be used to connect the sign display member to the base member.
