One-Way Traffic

"This is the most logical use of the old classic CRAZY COMPASS effect. Size approximately eight inches square. We have produced this on durable gleaming white plastic with the correct blue to match our normal road signs. As the sign is turned around the arrow points first in this direction, then that. A great comedy effect for any type of audience. A time tested comedy classic. LARGE ENOUGH TO BE CLEARLY SEEN Complete easy to follow instructions plus comedy patter."
