This is a River Backdrop, Number 5 in the adjoining series of 12. Number 1 will join to number 12, to make continuous placing possible. Some backdrops have smoke and nightwindows.
The backdrop is 180 metres long and approximately 35 metres high. A baseboard of 720 metres accommodates four backdrops. The rotation point is at the left hand end of the plane. It is height adjustable.
Place the backdrop, and slide it to the edge of the baseboard, it will lock into place. Adjust the height to suit, to you can lower the river water below the ground if required. Place the next adjoining backdrop to butt closely with the first and adjust the height to suit. Note that some backdrops have names on the buildings, these will appear reversed when viewed from the opposite side.
Once installed you will find it as Backdrop River 5 in the Australia scenery listing.
