neon signs in metal cans feature multi-colored, hand blown neon tubing. Each sign has a full color backround, which makes this sign beautiful to look at whether it is turned on or off. The Welcome to Fabulous Las Vegas neon sign measures 39 inches wide by 33 inches tall, and the red, yellow, white and blue neon tubes are surrounded by a sturdy, commercial grade shaped black steel housing. All you do is hang it up and plug it in – no assembly or special wiring required. neon signs have a warm mesmerizing glow, and are powered by industrial strength transformers, which operate silently and more efficiently than incandescent bulbs. For the collector who want the best and biggest neon money can buy! For indoor use only.
