Pole is a thick fiberglass rod. The end could be a plastic sign or silk screened sign but it must not flap in the wind so a thin bent fiberglass rod around it would be good. Sign could be round or oval at the end or square like in the picture. The sign on the end would need to stand up and not fold up when erected.
The bottom would need to be able to be hit with a hammer to put it into the ground. The stake would be have to be long enough to go into the ground to hold up the sign.
Hight is 4 teet.
