Measures 48"x24". Screen printed on steel; NOT porcelain.

Estimates on value?

Thanks,

...IMO, not too much - as it appears to be of recent, 'nostalgic' manufacture...the sign seems rather improbable: at an airport 'back in the day', where would such a sign have been used? and why are the colors on the Smith-O-Lene logo reversed?

...I may very well be wrong, but it just looks like something made up for a restaurant or bar, as decor...

Computer fonts used on the sign doesn't give it much hope as being original either......
