Abstract: A carrier for real estate signs is mounted on the back of a motor vehicle to allow signs to be carried outside the vehicle rather than inside the vehicle. This keeps the dirty or wet signs from soiling the vehicle. The carrier may be mounted to a trailer hitch. The carrier has two ends to capture the two ends of the sign. The ends are adjustable relative to one another, preferably by sliding them apart or together. One end, such as a retaining end, has holes to allow the sign legs to pass through, and thereby retain the signs from sliding off the other end, such as the channel or tray end.
