    • A sign waving machine platform for street side promotions that incorporates a base frame, a sign waving apparatus plus an upper web to attach accessories including mannequins and electric signs. The sign waving apparatus includes a motor housing, battery, electric motor and bracket assembly that couples the motor drive shaft to a sign frame which moves relative to the housing as the motor drive shaft rotates. Signs can be attached to all sides of the sign frame. The platform attaches at the top only to posts, carts and other so it can freely swing in many directions with the wind. This rugged, lightweight platform has a primary structure made from 2 aluminum tubes; one slides inside the other and telescopes. Fastening occurs using thumb screws attached to the outer tubes and joints that when twisted, pinches the inside interconnecting tubes. The platform stretches in many directions providing numerous configurations.
