Let's say you have a large den, home to automotive art, artifacts, and models. Or a garage in which you keep and maintain your beautiful collector cars. And let's say you've always had a nostaligic fondness for those old neon garage signs that were once common on repair shops and corner gas stations. You'd be delighted to have one hanging in that den or garage (or even your living room, if you're so inclined). Now you can. It won't be an original - they're getting to be rare and expensive as enthusiasts grab them up - but your garage sign will look just as good and by ordering from Cornhusker Sign and Manufacturing Co. of Gretna, Nebraska, you'll have a choice of styles and colors. There are two sizes: 48" long by 24" high by 8" deep and 34" long by 24" high by 8" deep. Prices average $550 and custom designs are available.
