Did you know that the iconic Citgo sign was originally a green & white Cities Service sign? The sign was built in 1940 at the site of the Cities Service divisional office, and wasn’t changed to the modern Citgo design until 1965. Ask your parents or grandparents about the Citgo sign, and you’re likely to met with something along the lines of, “The Citgo sign? Please. I remember when that was the old Cities Service sign”. Since then the sign has been threatened by fire, tornadoes, and even plans to remove the sign. But our beloved sign still remains!
