BTT. Anyone have any ideas on this restroom sign. I purchased it from a major gas and oil collector who collected mostly Sinclair. I know some companies changed there styles through the years, and I can't figure this one out.

I tried to go through a few companies that used green, such as: Buffalo, Cities, Conoco, Indian, Marathon, Polly, Shamrock, Sinclair, Texaco, to name a few, but I cant find anything.

Any help would be greatly appreciated.

Thank you,
Steve
