A mobile sign is adapted from discarded cotton collection trailers. The cotton collection trailers include a front steering axle and trailing rear axle supporting a horizontal rectangular frame. The rectangular cotton collection cage mounted to the trailer is removed and replaced with an upright vertical rectangular frame which supports sign material. The modifications to unused and discarded cotton collection trailers provides a useful purpose for the trailers and prevents the waste of selling the trailers for scrap. The trailers are easily pulled to desired locations utilizing the existing tow bar and can be secured by deploying outriggers or extendable feet, removing the tires from the trailer, and securing the trailer to a ground anchor. The mobile sign will support numerous types of sign material, including border grommeted canvas and board material.
