Primarily Petroliana Shop Talk Forums Shop Talk Petroliana Forums General Petroliana Discussion Meaning and date of Cities Service slogan and sign

I just picked up this Cities Service sign. I was wondering about the dating of the sign and information about the slogan "Once Always". Also how rare this sign may be? Any help would be greatly appreciated.
Thanks

Definitely a less common Cities Service sign. I've only seen a handful of them through the years. The Cities Service Once Always logo was used from the 20's up through 30's, so I'd date this sign in the middle of that same range,

It's a cool one I don't have in my collection. Great job on the find!

Thanks Sandman...do you know when Cities Service began using the slogan "Once Always" and when they stopped?

Sorry Sandman...I went back and read your post again and realized you had already answered my question. I am getting forgetful in my old age!!!
